First, a first embodiment of the present invention will be described. In the drawings, the same reference numerals represent the same functions. FIG. 1 is a diagram schematically showing a configuration of a computer system according to the present embodiment.

  FIG. 4A is a diagram showing an example in which a mobile phone and an input / output device are connected by wire. As shown in the figure, the mobile phone 1 includes a keyboard 11, an LCD (Liquid Crystal Display) 12, a changeover switch 13, and an external device interface 14. The input / output device 2 includes a keyboard 21, an LCD 22, an input / output interface 23, and a circuit and a power source therein. The input / output device 2 is configured such that a first housing 2 a that accommodates an LCD 22 and a second housing 2 b that accommodates a keyboard 21 are rotatably connected via a hinge portion 24. In appearance, it has the same shape as a general notebook PC.

  As will be described later, the cellular phone 1 has a microprocessor and data communication functions such as voice (music) data, text data, still image data, and moving image data. The cellular phone 1 and the input / output device 2 are connected by an interface cable 15 via the external device interface 14 and the input / output interface 23, and function as a virtual PC.

In the figure, an external device interface 14 and an input / output interface 23 are interfaces for performing wireless communication. The mobile phone 1 and the input / output device 2 are connected wirelessly via the external device interface 14 and the input / output interface 23, and function as a virtual PC. At the time of wireless connection, Bluetooth standard, wireless Universal Serial Bus (abbreviated as USB) standard, IEEE802.1 standard or the like can be adopted.

  The mobile phone 1 is also provided with a changeover switch 13 for switching between the operation of the keyboard 11 and the LCD 12 of the mobile phone 1 and the operation of the keyboard 21 and the LCD 22 of the input / output device 2. When the changeover switch 13 enables the keyboard 11 and the LCD 12 of the mobile phone to operate, the mobile phone is operated by the keyboard 11 and the LCD 12 like a general mobile phone. When the changeover switch 13 disables the operation of the input / output device 2 by disabling the keyboard 11 and LCD of the mobile phone, the input / output device can be operated, and the input signal from the keyboard 21 is input / output interface. 23 and the external device interface 14 via the cable 15 or wirelessly to the internal microprocessor to execute processing related to the communication function and predetermined processing corresponding to the input signal. The image is displayed on the LCD 22 by the cable 15 or wirelessly via the external device interface 14 and the input / output interface 23. In this manner, a virtual computer system is realized by the microprocessor of the mobile phone 1 and the input / output device 2. In this example, the operation of the keyboard 11 and the LCD 12 of the mobile phone 1 and the operation of the keyboard 21 and the LCD 22 of the input / output device 2 are switched by the changeover switch 13. It is also possible to use a switching method.

  FIG. 2 is a diagram showing an example in which a plurality of peripheral device interfaces 25 are provided so that peripheral devices can be connected to the input / output device 2 and operated. With this configuration, various peripheral devices connected to the peripheral device interface 25 can be operated by the microprocessor of the mobile phone 1. In this example, for example, the auxiliary storage device 26 including the HDD, the CD drive, the DVD drive, and the like and the printer 27 are operated. In the mobile phone 1 and the input / output device 2, when the auxiliary storage device 26 and the printer 27 are connected to the input / output device, settings necessary for operating the auxiliary storage device 26 and the printer 27 are automatically set by the plug and play function. Done.

FIG. 3 is a block diagram showing a configuration of the mobile phone 1 in the present embodiment.
As shown in the figure, a mobile phone 1 includes an interrupt control unit 302, a timer 303, a DMAC (Direct Memory Access Controller) 304, a microprocessor 301 including a CPU (Central Processing Unit) 305, an antenna 306, and an RF (Radio Frequency). Signal processing unit (hereinafter referred to as RF unit) 307, baseband modem 308, switching control unit 309, DSP (Digital Signal Processor) 310, RAM 311, ROM 312, audio control unit 313, speaker 314, microphone 315, MPEG-4 (Moving Picture Experts Group phase 4) The control unit 316, the camera 317, the keyboard 11 and the LCD 12, the DMA bus 320, the program IO (Input / Output) bus 321, the external device interface 14, and the power supply 323 are configured. Connected through. The RAM 311 is used as a temporary storage device during the processing of the microprocessor 301, downloaded from a communication partner (for example, a Web server on the center side that provides various services), or from an external storage device such as a CD drive. The read application program is stored. The ROM 312 supplies a BIOS necessary for the operation of the mobile phone 1, device drivers for peripheral devices connected to the input / output device 2, and necessary initial setting values (default values). The power supply 323 is supplied to and operated by all functions of the mobile phone 1.

  The incoming call operation of the cellular phone 1 is received by the RF unit 307 that processes a high-frequency analog signal when a call radio wave arrives at the antenna 306, undergoes analog-digital conversion, is demodulated by the baseband modem 308, and is processed by the microprocessor. This is performed by being transmitted to 301. When the reception signal is transmitted to the microprocessor 301, the CPU 305 performs a series of reception operations. The interrupt control unit 302 performs incoming interrupt control, and the timer 303 monitors the communication time.

  When the incoming call is a voice call, the microprocessor 301 controls the audio control unit 313 and the speaker 314 to reproduce via the program IO bus 321. When the audio signal is compressed in the case of music or the like, it is decompressed by the DMAC 304 and the DSP 310. When the incoming call is a video (moving image), the microprocessor 301 controls the MPEG-4 control unit 316 and the LCD 12 to display the video via the program IO bus 321. When the video signal is compressed, it is decompressed and displayed by the DMAC 304, the DSP 310, and the MPEG-4 control unit 316. When the incoming call is data, the DMAC 304 operates to store the data in the RAM 311 via the DMA bus 320, and controls the MPEG-4 control unit 316 and the LCD 12 to display the data via the program IO bus 321.

  The transmission operation of the mobile phone 1 is performed by transmitting a transmission signal to the microprocessor 301. When the transmission signal is transmitted to the microprocessor 301, the CPU 305 performs a series of transmission operations. The outgoing signal is modulated by the baseband modem 308, converted from digital to analog by the RF unit 307, and emitted from the antenna 306. In the microprocessor 301, transmission interrupt control is performed by the interrupt control unit 302 under the control of the CPU 305, and the communication time is monitored by the timer 303.

  When the call is a voice call, a voice signal is sent to the microprocessor 301 via the microphone 315, the audio control unit 313, and the program IO bus 321, and the above call operation is performed. When the transmission is an image from the camera 317, a signal is sent to the microprocessor 301 via the MPEG-4 control unit 316 and the program IO bus 321, and the above transmission operation is performed. If the transmission is data input from the keyboard 11, the data is sent to the microprocessor 301 via the program IO bus 321, and the transmission operation is performed. For example, when the transmission is a mail stored in the RAM 311, data is sent to the microprocessor 301 via the DMA bus 320 and the transmission operation is performed.

  The switching control unit 309 selects the operation of the input / output device 2 and part or all of the keyboard 11 and the LCD 12 of the mobile phone 1. The external device interface 14 connects the mobile phone 1 and the input / output device 2.

FIG. 4 is a diagram illustrating a configuration of the switching control unit 309 according to an embodiment of the present invention.
As shown in the figure, the AND circuit 401 is connected to a cellular phone keyboard interrupt signal and the signal of the changeover switch 13. The AND circuit 402 is connected to the mobile phone LCD interrupt signal and the signal of the changeover switch 13. After the logical operation is performed, these output signals are sent to the interrupt control unit 302 as an authorized mobile phone keyboard interrupt signal and an authorized mobile phone LCD interrupt signal.

  The AND circuit 403 is connected to the input / output device interrupt signal and the signal of the changeover switch 13. After the logical operation is performed, this output signal is sent to the interrupt control unit 302 as a permitted input / output device interrupt signal. Either the AND circuits 401 and 402 or the AND circuit 403 is selectively operated by the operation of the changeover switch 13. The keyboard 11 and the LCD 12 of the mobile phone 1 can operate when the interrupt signal is permitted. Similarly, the input / output device 2 becomes operable when the interrupt signal is permitted. Conversely, the keyboard 11 and LCD 12 of the mobile phone 1 that cannot send an interrupt signal cannot operate, and similarly, the input / output device 2 that cannot send an interrupt signal cannot operate. Thus, by operating the changeover switch 13, the keyboard 11 and LCD 12 of the mobile phone 1 and the input / output device 2 can be selectively operated.

  FIG. 5 is a block diagram showing the configuration of the input / output device 2 in the present embodiment.

  As shown in the figure, the input / output device 2 includes the input / output interface 23, a PnP control unit 702, a ROM 703, a graphic control unit 704, the keyboard 21 and the LCD 22, a program IO bus 707, and a power source 708. Connected through. The power supply 708 is supplied to and operated by all functions of the input / output device 2.

  As described above, the external device interface 14 of the mobile phone 1 and the external device interface 14 of the input / output device 2 are connected by wire or wirelessly, and the microprocessor 301 includes the program IO bus 321 of the mobile phone 1 and the input / output device. The input / output device 2 is operated via the second program IO bus 707 to transfer data.

  The PnP control unit 702 transmits and receives signals to and from the microprocessor 301 when the input / output device 2 is turned on, and the device address, interrupt address and priority of the input / output device 2, allocation of resources, allocation of device drivers, and the like are necessary. The setting is automatically performed so that the microprocessor 301 can operate the input / output device 2. Further, even when peripheral devices such as the auxiliary storage device 26 and the printer 27 are connected to the peripheral device interface 25 when the power of the input / output device 2 is turned on, the input / output device 2 exchanges signals with the microprocessor 301. And the necessary settings are automatically performed so that the microprocessor 301 can operate the input / output device 2 and peripheral devices.

  The ROM 703 stores a BIOS necessary for operating the input / output device 2 and a device driver necessary for operating the input / output device 2 and peripheral devices. The microprocessor 301 is activated when the input / output device 2 is started. Is loaded into the RAM 311 and used. Depending on the peripheral device, the ROM 703 may not have a device driver. At that time, the microprocessor 301 searches the ROM 312 of the mobile phone 1 and, if there is not, downloads it from the communication partner (center side) of the mobile phone 1.

  The graphic control unit 704 has a video memory, generates RGB signals from display data sent from the mobile phone 1, and sends them to the LCD 22 for display. The keyboard 21 sends an input signal to the microprocessor 301 of the mobile phone 1 to start processing related to a communication function or a program determined in advance corresponding to the input signal to execute processing. The processing result output from the microprocessor 301 is displayed on the LCD 22.

  Next, operations of the mobile phone 1 and the input / output device 2 in the present embodiment will be described. FIG. 6 is a diagram showing a basic operation flow of the mobile phone 1 and the input / output device 2 in the present embodiment.

  As shown in the figure, in this embodiment, the priority of the communication function of the mobile phone 1 is set high. When the mobile phone 1 receives an incoming call, communication processing is performed (step 1201), and the state of the changeover switch 13 is checked. If the mobile phone 1 is selected by the changeover switch 13, the display is made on the LCD 12 of the mobile phone 1 (step 1202). If the input / output device 2 is selected by the changeover switch 13, the display is made on the LCD 22 of the input / output device 2. If there is a peripheral device operation request, the peripheral device is operated (step 1204).

  Subsequently, it is checked whether there is an input by a user operation (step 1205). If there is an input, the state of the changeover switch 13 is checked. If the cellular phone 1 is selected by the changeover switch 13 and there is a key input from the cellular phone 1, a key input process on the keyboard 11 of the cellular phone 1 is performed (step 1206). If the input / output device 2 is selected by the changeover switch 13 and there is a key input from the input / output device 2, a key input process is performed on the keyboard 21 of the input / output device 2 (step 1207). The peripheral device is operated (step 1208).

  Note that the above is a basic flow, and emergency processing can be performed by interrupt processing without depending on this flow. These flows are controlled by the microprocessor 301.

  Hereinafter, operations of the mobile phone 1 and the input / output device 2 will be described in more detail. FIG. 7 is a flowchart showing an operation main routine of the mobile phone 1 and the input / output device 2 in the present embodiment.

  As shown in the figure, when the mobile phone 1 is turned on (Yes in step 1301), the microprocessor 301 checks the power supply of the input / output device 2. If it is turned on (Yes in step 1302), the microprocessor 301 performs PnP processing between the input / output device 2 and peripheral devices connected to the input / output device 2 (step 1303).

  Subsequently, the microprocessor 301 checks whether or not there is an incoming call to the mobile phone 1, and if there is an incoming call (Yes in step 1304), the microprocessor 301 performs a process for mobile communication (step 1305), and a display process to be described later. A subroutine is executed (step 1306), and a peripheral device operation subroutine described later is executed (step 1307). When the series of processing ends (Yes in step 1308), the microprocessor 301 executes a key input processing main routine (described later) when the input / output device 2 is powered on (step 1309). Even when there is no incoming call from the mobile phone 1 (No in step 1304), the microprocessor 301 executes a key input processing main routine when the power of the input / output device 2 is turned on (step 1309).

  On the other hand, when the input / output device 2 is not powered on (No in step 1302), the microprocessor 301 checks whether there is an incoming call to the mobile phone 1, and if there is an incoming call (Yes in step 1310), the microprocessor The mobile communication processing is performed by step 301 (step 1311), the display processing subroutine is executed (step 1312), and the peripheral device operation subroutine is further executed (step 1313). When the series of processing ends (Yes in step 1314), the microprocessor 301 executes a key input processing main routine (described later) when the power of the input / output device 2 is turned off (step 1315). Even when there is no incoming call from the mobile phone (No in step 1310), the key input processing main routine when the power of the input / output device 2 is turned off is executed (step 1315).

  FIG. 8 is a flowchart showing a key input processing main routine when the input / output device 2 is powered on in the present embodiment.

  As shown in the figure, when there is a key input (Yes in step 1401), the microprocessor 301 checks whether the input is a key input of the mobile phone 1, and in the case of the key input of the mobile phone 1 (in step 1402). Yes), it is checked by the microprocessor 301 whether the change-over switch 13 is set to be able to operate the mobile phone. If the mobile phone is operable (Yes in step 1403), the microprocessor 301 performs key input processing of the mobile phone 1 via the keyboard 11 (step 1404), and then the peripheral device operation subroutine is executed (step 1404). Step 1405).

  If the change-over switch 13 is set to disable the mobile phone operation (N in step 1403), the microprocessor 301 will indicate to the LCD 22 of the input / output device 2 that “the mobile phone key is invalid. Is displayed (step 1408), the key input process is interrupted (step 1409), and the process proceeds to the main operation routine of the mobile phone 1 shown in FIG. When the series of processing is completed (Yes in step 1406), the microprocessor 301 checks whether the power of the mobile phone is turned off, and when it remains on (Yes in step 1407), the mobile phone in FIG. 1 moves to the main operation routine. If turned off (N in S1406), the process ends.

  If the key input is not for the mobile phone 1 (No in step 1402), since the key input is from the input / output device 2, is the changeover switch 13 set to disable the mobile phone (that is, the input / output device 2 can be operated)? Is examined by the microprocessor 301. If the input / output device 2 is operable (No in step 1411), key input processing is performed via the keyboard 21 of the input / output device 2 (step 1412), and the peripheral device operation subroutine is subsequently executed. If the change-over switch 13 is set to be able to operate the mobile phone (Yes in step 1411), the microprocessor 301 (determines that the setting is wrong) to the LCD 12 of the mobile phone 1 "I / O device is invalid. An error message such as “Setting” is displayed (step 1413), the key input processing is interrupted (step 1414), and the operation shifts to the operation main routine of the mobile phone 1 shown in FIG.

  FIG. 9 is a flowchart showing a key input processing main routine when the input / output device 2 is turned off in the present embodiment.

  As shown in the figure, when there is a key input (Yes in step 1501), the microprocessor 301 checks whether the change-over switch 13 is set to enable the mobile phone 1. If the mobile phone 1 is operable (Yes in step 1502), key input processing via the keyboard 11 of the mobile phone 1 is performed under the control of the microprocessor 301 (step 1503). When the series of processing is completed (Yes in step 1506), the microprocessor 301 checks whether the power of the mobile phone is turned off, and when the power is kept on (Yes in step 1507), FIG. The operation main routine of the mobile phone 1 is moved to. If it is turned off (No in step 1507), the process ends.

  When the change-over switch 13 is set to be inoperable for the mobile phone (No in step 1502), the microprocessor 301 (determines that the setting is incorrect) via the speaker 314 of the mobile phone 1 A voice message such as “Telephone key is invalid” is output (step 1504), the key input process is interrupted (step 1505), and the process proceeds to the main operation routine of the mobile phone 1 shown in FIG.

FIG. 10 is a flowchart showing a subroutine of display processing in the present embodiment.
As shown in the figure, when there is a display process (Yes in step 1601), the microprocessor 301 checks whether the changeover switch 13 is set to be operable in the mobile phone. If the mobile phone is operable (Yes in step 1602), the microprocessor 301 performs display processing on the LCD 12 of the mobile phone 1 (step 1603), and returns to the main routine that called the subroutine.

  If the change-over switch 13 is set to be inoperable (No in step 1602), the microprocessor 301 checks whether the power of the input / output device 2 is ON. If it is ON (Yes in step 1604), the micro switch Display processing on the LCD 22 of the input / output device 2 is performed by the processor 301 (step 1605), and the process returns to the main routine that called the subroutine. When the power supply of the input / output device 2 is OFF (when the power supply is turned OFF for some reason such as out of charge or incorrect operation), the microprocessor 301, for example, “There is a display request to the input / output device. A voice message such as “the device is turned off” is output via the speaker 314 of the mobile phone 1 (step 1606), the display process is interrupted (step 1607), and the main operation routine of the mobile phone 1 from FIG. Move on.

FIG. 17 is a flowchart showing a subroutine of peripheral device operation in the present embodiment.
As shown in the figure, when there is a peripheral device operation request (Yes in Step 1701), the microprocessor 301 checks whether the power supply of the input / output device 2 is ON. When it is ON (Yes in Step 1702), It is checked whether the peripheral device is powered on. When the power is on (Yes in step 1703), it is checked whether the changeover switch 13 is set to be able to operate the mobile phone. If the mobile phone is inoperable (No in step 1704) (because the input / output device 2 can operate), the microprocessor 301 performs the peripheral device operation processing including loading the peripheral device driver (step 1705), the process returns to the main routine that called the subroutine.

  When the power of the input / output device 2 is OFF (No in step 1702), the microprocessor 301 sends an error message to the LCD 12 of the mobile phone 1 such as “There is a peripheral device operation request but the input / output device power is OFF”. Display is performed (step 1710), operation processing of peripheral devices is interrupted (step 1711), and the operation main routine of the mobile phone 1 is started.

  When the power supply of the peripheral device is OFF (No in Step 1703), the microprocessor 301 checks whether the changeover switch 13 is set to be able to operate the mobile phone. When the mobile phone is operable (Yes in Step 1707), the microprocessor 301 displays an error display on the LCD 12 of the mobile phone 1 such as “I / O device is disabled” or “Peripheral device power is OFF”. (Step 1708), the operation processing of the peripheral device is interrupted (step 1711), and the operation main routine of the mobile phone 1 is started.

  If the mobile phone is inoperable (No in step 1707), the microprocessor 301 displays, for example, “Peripheral device power is OFF” on the LCD 22 of the input / output device 2 (step 1709), and performs peripheral device operation processing. The operation is interrupted (step 1711), and the operation main routine of the mobile phone 1 is started.

  If the mobile phone is operable (Yes in step 1704), the microprocessor 301 displays an error message on the LCD 12 of the mobile phone 1 such as "I / O device is invalid" (step 1706) The operation processing of the device is interrupted (step 1711), and the operation main routine of the mobile phone 1 is started.

  Above, description of operation | movement of the mobile telephone 1 in this embodiment and the input / output device 2 is complete | finished.

  With the configuration and operation described above, the computer system according to the present embodiment has the following effects.

  The first effect is the superiority of technical or intellectual assets such as various standards, functions, interfaces, programs, data, data representations, peripheral devices, and operation methods established so far in the PC and mobile phone fields. It is possible to create new value by selectively inheriting and utilizing the products. For example, a communication function of a mobile phone allows a large-scale application program that has been impossible to achieve with a mobile phone to be downloaded to an input / output device and executed. In addition, in order to use Internet browsers, games and business software developed for PCs on mobile phones, it has been necessary to redesign programs and data in accordance with mobile phone display devices. By adopting a screen of the same standard as the PC (referred to as VGA, SGA, XGA, etc. in the technical field) for the display device of the input / output device, the porting work can be greatly reduced. Furthermore, since each function including the keyboard is released from physical restrictions, the user interface and accessibility can be greatly improved.

  The second effect is that the computing resources of the mobile phone in the standby mode can be utilized to the maximum extent. The mobile phone and the input / output device can perform parallel processing by establishing not only one-to-one connection but also one-to-multiple, multiple-to-one, and multiple-to-multiple connections. In a typical example, a computing system called a “server computing” or a “network computing” in the computer technology field in the case of one-to-many, a mobile phone or computing of a communication partner (center side) A system with high cost performance using resources as a server can be realized. In the case of multiple one-to-one, parallel processing called “multiple programming multiple processing” in the computer technology field can be realized. In the case of multiple-to-multiple, a high-speed and large-capacity information processing system that simultaneously uses multiple computing resources called “grid computing” in the computer technology field can be realized.

  The third effect is that a “simultaneous broadcast communication” system can be realized when the mobile phone and the input / output device are connected in a one-to-multiple manner using the characteristic that the mobile phone is owned by each individual. is there. In the case of multiple one-to-one, a “command system” can be realized. Furthermore, in the case of multiple to multiple, a “conference system” can be realized.

  The fourth effect is an energy saving effect. Much of the power consumption of the PC is due to the mounted microprocessor. By saving this and sharing it with the microprocessor mounted on the mobile phone, significant energy saving can be realized.

  A fifth effect is that the functions and functions of the mobile phone and the input / output device are shared, so that the architecture and implementation of each can be simplified and simplified. As a result, the mobile phone can be further enhanced in function, lightness, and smallness, and the input / output device can be equipped with all necessary functions according to applications such as business use and hobby use.

  The sixth effect is that the input / output device can be used on the lap while the mobile phone is put in a pocket or a bag by adopting wireless for the interface between the mobile phone and the input / output device.

  The seventh effect is that not only a conventional pay OS but also an OS that becomes open source software can be adopted as the OS (Operating System) of the computer system in the present embodiment. A variety of application programs can be developed by making full use of technologies adopted in mobile phones called Java (registered trademark) and BREW (registered trademark).

  The eighth effect is that the OS of the computer system in this embodiment and the OS for operating the communication function of the mobile phone may be the same or different, and a so-called Dual-OS system can be obtained. . For example, a high-speed and robust real-time OS can be used as an OS for operating a communication function, and a multi-task OS that emphasizes compatibility with a PC can be used as an OS for a virtual personal computer system or virtual personal computer device.

  The ninth effect is improvement of the business model. First, by physically separating the mobile phone and the input / output device, it was possible to develop and develop the input / output device of the present invention for companies that have not been able to enter the development and manufacturing of mobile phones due to the complexity of the system. The manufacturing door will be greatly opened. Next is the eradication of illegal copies of content or software. Since the input / output device of the present invention does not have a microprocessor for executing a program, it is necessary to always use a mobile phone for copying. In this case, for example, in the case of paid software, if a mechanism that enables copying for the first time after confirmation with the communication partner (center side) is incorporated into the mobile phone, proper distribution of content or software, including charging problems, will be carried out. Can be promoted.

  The tenth effect is that so-called TCO (Total Cost of Ownership) such as upgrade costs, labor costs of system departments and system administrators is improved and compatible. The BIOS, driver, OS, and application program stored in the mobile phone or input / output device can be managed and updated in a batch by downloading from the center using the mobile phone communication function, so TCO can be significantly improved. . Even if an input / output device manufactured by a manufacturer different from the input / output device manufactured or certified by the mobile phone manufacturer is not guaranteed to operate as it is, an appropriate BIOS, driver, OS, and application program are input from the center side. Compatibility can be ensured by downloading to the output device.

  The eleventh effect is information protection. For example, when a mobile phone is lost, information leakage can be prevented by deleting the memory of the mobile phone from the center side. Also, in case the input / output device is lost, information leakage can be prevented by setting the mobile phone of the connection partner and the encryption key so that other people cannot use the input / output device. At the same time, if the mobile phone and the input / output device are lost, information storage can be prevented by deleting both memories from the center and locking the download.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. FIG. 12 is a diagram showing the configuration of the input / output device 2 in the present embodiment. Note that in the present embodiment and the embodiments described below, the same reference numerals are given to the same components and functions as in the first embodiment, and the description will be omitted or simplified.

  As shown in the figure, in this embodiment, the input / output device 2 is equipped with a USB interface 801 and a wireless LAN interface 802 so that peripheral devices can be connected and operated. Connect and operate peripheral devices wirelessly. As in the case of the first embodiment, the device driver necessary for the operation is downloaded by the communication function of the mobile phone 1, stored in advance in the ROM 312 of the mobile phone 1, or the input / output device 2 The data is loaded from the ROM 703 to the RAM 311 by one of the methods, and is executed by the microprocessor 301.

  In the present embodiment, the configuration of the mobile phone 1 and the other operations of the microprocessor 301 are the same as those in the first embodiment, and a description thereof will be omitted.

Next, a third embodiment of the present invention will be described. FIG. 13 is a diagram showing the configuration of the input / output device 2 in the present embodiment.

  As shown in the figure, in the present embodiment, a wireless Bluetooth interface (hereinafter referred to as BT interface) 903 is connected to the audio control unit 902, and a hands-free receiver 904 and a microphone 905 are connected. Voice communication can be performed while operating the keyboard 11. A camera 901 is also connected to the graphic control unit 704, and can capture and process a captured image.

  In the present embodiment, the configuration of the mobile phone 1 and the other operations of the microprocessor 301 are the same as those in the first embodiment, and a description thereof will be omitted.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described. In this embodiment, a new interface is provided for each of the mobile phone 1 and the input / output device to improve the throughput of the entire system.

FIG. 14 is a diagram showing a configuration of the mobile phone 1 according to the present embodiment.
As shown in the figure, in this embodiment, in addition to the external device interface 322 connected to the program IO bus 321 in the first embodiment, the external device interface 16 connected to the DMA bus 320 is added. ing. The external device interface 14 connected to the program IO bus 321 is simple in terms of logical circuit structure, but for example, by high-speed and large-capacity data transfer between the mobile phone 1 and the input / output device 2 such as when transferring moving images As a result, a load is applied to the program IO bus 321, which may adversely affect the operation of the mobile phone 1. In order to avoid this, an external device interface 16 connected to the DMA bus 320 is added, and high-speed and large-capacity data transfer is performed via the external device interface 16.

FIG. 15 is a diagram showing a configuration of the input / output device 2 in the present embodiment.
As shown in the figure, a program IO bus 321 and a program IO bus 707 are connected via an external device interface 14 and an input / output interface 23 of the mobile phone 1, and a DMA bus 320 of the mobile phone 1 is A DMA bus 1006 is realized by connecting to the external device interface 16 via the input / output interface 23 of the input / output device 2, and in addition to the PnP control unit 702 and ROM 703, a DSP 1002, RAM 1003, and auxiliary storage control unit 1004 are provided. The auxiliary storage device 26 is connected via the auxiliary storage control unit 1004.

  Transfer of large-capacity data between these units and the DSP 310, RAM 311 and ROM 312 of the mobile phone 1 is performed via the DMA bus 1006 under the control of the DMAC 304. The DSP 1002 is used via the DMA bus 1006 during audio data processing and graphic data processing. Thus, the overall throughput can be improved by controlling the microprocessor 301 so that high-speed and large-capacity data transfer is performed not via the program IO bus 707 but via the DMA bus 1006.

  In addition to data such as music, still images, and moving images, the RAM 1003 can store an application program downloaded from a communication partner (center side) or read from the auxiliary storage device 26. There are two ways to execute the stored program.

  The first method is a method in which the physical addresses of the RAM 311 of the mobile phone 1 and the RAM 1003 of the input / output device 2 are made continuous and called to the microprocessor 301 for each instruction. In order to reduce the influence of the delay time of the DMA bus 320 and the external device interface 16 of the mobile phone 1, the input / output interface 28 of the input / output device 2 and the DMA bus 1006, the microprocessor 301 adopts an instruction cache method, Burst transfer is performed from the RAM 1003 to the instruction cache memory.

  In the second method, the RAM 1003 of the input / output device 2 is configured as a virtual memory (including the auxiliary storage device 26 if necessary), and a logical address is assigned while swapping with the RAM 311 of the mobile phone 1. It is a method to execute. For further high-speed processing, each program in the RAM 1003 is transferred to the RAM 311 and executed. In order to shorten the response time of each program, each program process is transferred to the RAM 311 (loaded into the RAM 311) to execute parallel processing.

  In the present embodiment, the configuration of the mobile phone 1 and the other operations of the microprocessor 301 are the same as those in the first embodiment, and a description thereof will be omitted.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described. In the present embodiment, a device for further improving the throughput is provided as compared with the case of the fourth embodiment.

FIG. 16 is a diagram showing a configuration of the mobile phone 1 according to the present embodiment.
As shown in the figure, in this embodiment, in addition to the external device interface 14 connected to the program IO bus 321 in the first embodiment, the external device interface connected to the high-speed bus 601 directly connected to the CPU 305. 17 has been added. The external device interface 17 is logically combined with the external device interface 14 to form three types of low-speed, medium-speed, and high-speed dedicated buses inside the input / output device 2, and further transfer large-capacity and high-speed data. To be able to. This function is particularly effective when a tuner is connected to the input / output device 2 to receive TV broadcasts such as satellite digital TV broadcasts and mobile broadcasts.

FIG. 17 is a diagram showing a configuration of the input / output device 2 in the present embodiment.
As shown in the figure, the microprocessor 301 connects the program IO bus 321 of the mobile phone 1 and the program IO bus 707 of the input / output device 2, the external device interface 14 of the mobile phone 1 and the input / output interface of the input / output device 2. 23, and the external device interface 17 connected to the high-speed bus 601 in the mobile phone 1 and the input / output interface 29 of the input / output device 2 are connected to operate the bus management unit 1102. The bus management unit 1102 implements a DMA bus 1105, a medium speed bus 1104, and a program IO bus 1103. A DMA bus 1105 is used for high-speed and large-capacity data transfer such as the auxiliary storage device 26 connected via the ROM 703, DSP 1002, RAM 1003, and auxiliary storage control unit 1004. The medium-speed bus 1104 is used for medium-speed and medium-capacity data transfer such as the audio control unit 902, the USB interface 801, and the wireless LAN interface 802. The program IO bus 1103 is used for low-speed and small-capacity data transfer such as the keyboard 21.

  With this configuration, the load on the DMA bus 320 and the program IO bus 321 of the mobile phone 1 can be reduced, and the input / output device 2 uses different buses according to the characteristics of high-speed, medium-speed, and low-speed devices or devices. Therefore, the overall throughput can be further improved.

  In the present embodiment, the configuration of the mobile phone 1 and the other operations of the microprocessor 301 are the same as those in the first embodiment, and a description thereof will be omitted.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described. In the present embodiment, it is assumed that a plurality of mobile phones 1 and input / output devices 2 are used, and address designation for each device is performed. Note that in this embodiment, the configurations of the mobile phone 1 and the input / output device 2 are the same as those in the first embodiment, so that the description thereof will be omitted and only the operation will be described.

  FIG. 18 is a flowchart showing a key input processing main routine when the input / output device 2 is powered on in this embodiment. In addition, the same code | symbol is attached | subjected about the process similar to FIG. 8 of the said 1st Embodiment, and description is abbreviate | omitted.

  As shown in the figure, when there is a key input of the input / output device 2, the microprocessor 301 checks whether there is an address designation for the cellular phone 1, and when there is an address designation (Yes in step 1801), the input / output device. When the key input routine of No. 2 operates and there is no address designation (No in Step 1801), the microprocessor 301 moves to the mobile phone main routine. With this configuration, it is possible to specify a specific mobile phone from the input / output device 2 and input an input signal from the keyboard 21, for example, from one input / output device 2 to a plurality of mobile phones 1. Parallel processing called multiple programming and multiple processing can be realized.

  FIG. 19 is a flowchart showing a display processing subroutine in the present embodiment.

  As shown in the figure, when there is a display process on the input / output device 2, the microprocessor 301 checks whether there is an address designation for the input / output device 2, and if there is an address designation (Yes in step 1901), When the display processing subroutine for the output device 2 operates and there is no address designation (No in step 1901), the microprocessor 301 moves to the mobile phone main routine. With this configuration, it is possible to designate a specific input / output device 2 from the mobile phone 1 and display a display signal on the LCD 22 of the input / output device 2. Simultaneous broadcast communication to the device 2 becomes possible.

FIG. 20 is a flowchart showing a peripheral device operation subroutine according to the present embodiment.
As shown in the figure, when there is a peripheral device operation request, the microprocessor 301 checks whether there is an address designation for the input / output device 2. When there is an address designation (Yes in step 2001), the input / output device 2 is checked. When the operation subroutine of the connected peripheral device operates and there is no address designation (No in step 2001), the microprocessor 301 moves to the mobile phone main routine. With this configuration, it is possible to designate a specific input / output device 2 from the mobile phone 1 and operate peripheral devices connected to the input / output device 2.

  The present invention is not limited to the above-described embodiments and the like, and various modifications are possible.

  In the above-described embodiment, the display signal generated by the microprocessor 301 of the mobile phone 1 is displayed on the LCD 22. However, the input / output device is a combination of the keyboard 21 and another device capable of displaying the display signal. 2 may be configured.

  FIG. 21 is a diagram illustrating an example in which the input / output device 2 is configured by applying a projector as a display unit. As shown in the figure, the input / output device 2 includes a keyboard 21 and a liquid crystal projector 31. The cellular phone 1 and the keyboard 21 are connected via the external device interface 14 and the input / output interface 23, and the keyboard 21 and the liquid crystal projector 31 are connected via the peripheral device interface 25. A display signal generated by the microprocessor 301 of the mobile phone 1 based on an input signal from the keyboard 21 is output to the projector 31 via the keyboard 21, and a liquid crystal panel (not shown) inside the liquid crystal projector 31 and the lens 33. Is projected and displayed on an external screen (not shown).

  With this configuration, for example, during a presentation in a meeting, the content projected and displayed on the external screen can be edited (corrected) with the keyboard 21 and displayed on the external screen, and this is appropriately handled when there is an error in the presentation content. Can make presentations go smoothly.

  Further, as shown in FIG. 22, a keyboard 21 may be incorporated in a liquid crystal projector 31. In this case, the liquid crystal projector 31 may be provided with a cover 32 for covering the keyboard 21 when not in use to prevent malfunction.

  FIG. 23 is a diagram illustrating an example in which the input / output device 2 is configured by applying a liquid crystal television as a display unit. As shown in the figure, the input / output device 2 includes a keyboard 21 and a liquid crystal television 41. The cellular phone 1 and the keyboard 21 are connected via the external device interface 14 and the input / output interface 23, and the keyboard 21 and the liquid crystal television 41 are connected via the peripheral device interface 25. A display signal generated by the microprocessor 301 of the mobile phone 1 based on an input signal from the keyboard 21 is output to the liquid crystal television 41 through the keyboard 21 and displayed on the LCD 42 of the liquid crystal television 41.

  This makes it possible to construct a virtual PC system simply by carrying the mobile phone 1 and the keyboard 21 in a place where a liquid crystal television is present, such as a living room in the home.

  In the above-described embodiment, the LCD is used for the display unit, but other display devices such as a CRT may be used. The mobile phone 1 is a so-called straight type mobile phone in which the LCD 12 and the keyboard 11 are provided on the same surface. However, as shown in FIG. 31, in addition to the so-called folding type, a sliding type, a rotary open type, etc. Various forms can be taken.

  In the computer system according to the above embodiments, wireless communication is performed with the center side, and the operation of the mobile phone or the input / output device is changed from the normal operation, or the operation itself is permitted or not permitted. Thus, a computer system capable of controlling the operation from the center side can be provided. In the following description, it is assumed that the ROM 312 is configured by a flash memory.

  The first application example of the computer system configured as described above is virus infection monitoring (hereinafter referred to as local virus monitoring) on the user side such as an application program and mail.

FIG. 24 shows the flow of local virus monitoring.
The mobile phone 1 stores in advance in the ROM 312 a computer virus definition file obtained from the center side by wireless communication based on an input signal from the keyboard 11 or the keyboard 21. Based on an input signal from the keyboard 11 or the keyboard 21, the microprocessor 301 compares the virus definition file stored in the ROM 312 with the program and related data before executing the program executed by the microprocessor 301. If the computer virus is not infected, the state is stored as “1” in the ROM 312, the “non-infection” information is displayed on the LCD 11 or the LCD 22, and the execution of the program is permitted and executed.
If the computer virus is infected, the state is stored as “0” in the ROM 312, “infection” information is displayed on the LCD 11 or LCD 22, execution of the program is prohibited, and the user removes the virus. Wait for. When removed, the state is stored as “1” in the ROM 312, “non-infection” information is displayed on the LCD 11 or LCD 22, and the execution of the program is permitted and executed.

As a result, the execution of a program infected with a virus can be prevented, or the infection of other programs or data can be prevented.
The microprocessor 301 performs wireless communication based on an input signal from the keyboard 11 or the keyboard 21, and updates the virus definition file stored in the ROM 301 based on the latest virus definition file obtained from the center side. Control.
This makes it possible to prevent the execution of a program infected with the latest virus or prevent infection of other programs or data with the latest virus.
The second application example of the computer system configured as described above is to monitor permission or prohibition of execution of a specific application program on the center side (hereinafter referred to as center program monitoring).

FIG. 25 shows a flow of center program monitoring.
Prior to execution of a program executed by the microprocessor 301 based on an input signal from the keyboard 11 or the keyboard 21, the microprocessor 301, the center side, the program name, the program body, the program part, Wireless communication of data including any or all of the keywords included in the program and the extension of the program is performed, and the execution permission or execution prohibition state of the program based on the center program monitoring result is received from the center side. If the execution is permitted, the state is stored as “1” in the ROM 312, “execution” information is displayed on the LCD 11 or the LCD 22, and the execution of the program is permitted and executed.

  If execution of the program is prohibited, the state is stored as “0” in the ROM 312, “prohibition” information is displayed on the LCD 11 or LCD 22, and execution of the program is prohibited.

  This prohibits access to personal information for private business use and access to Web pages that are not necessary for work. In addition, it is possible to manage permission or prohibition of the execution of so-called P2P (Peer to Peer) software on the center side by directly connecting computers and exchanging files with each other. For example, information leakage by Winny Can be prevented.

  A third application example of the computer system configured as described above is to prevent leakage by designating the confidentiality of company information, personal information and other highly confidential specific confidential information from the center side.

FIG. 26 shows a flow of state monitoring of specific density information.
The microprocessor 301 activates a program using specific confidential information such as customer data, which is executed by the microprocessor 301 based on an input signal from the keyboard 11 or the keyboard 21. When the specific confidential information is received, the microprocessor 301 stores the information and the accompanying confidential state in the ROM 312.

  There are state 1 and state 2 in the confidential state. State 1 indicates whether or not confidentiality is specified, “1” indicates presence, and “0” indicates absence. State 2 represents the height of the confidentiality in the confidentiality designation, and “1” indicates a high one and “0” indicates a low one.

When the execution of the program using the specific confidentiality information is completed, the microprocessor 301 checks the state 1, and if “0”, there is no confidentiality designation, so the specific confidential information stored in the ROM 312 is deleted. finish. If “1”, there is a confidentiality designation, so the microprocessor 301 checks state 2. If the state 2 is “1”, since the sensitivity is high, the microprocessor 301 erases the specific confidential information stored in the ROM 312 and ends. If the state 2 is “0”, the confidentiality is low, and the process ends without erasing.
Here, the operation end includes not only the operation end of the program but also power-off of the mobile phone or the input / output device, disconnection of the interface with the input / output device, and the like.

  As a result, information with high confidentiality can be erased at the end of the operation, and information with low confidentiality can be stored in the mobile phone. In addition, even if the mobile phone is accidentally lost, if the mobile phone is set to automatically turn off when not in use, sensitive information is automatically deleted, preventing leakage. Can do. Even if you forget to specify confidentiality, you can delete all specific confidential information.

  A fourth application example of the computer system configured as described above is reproduction of a moving image signal or an audio signal in which a digital watermark is embedded. Different operations are performed depending on the difference between so-called paid content such as movies and music embedded with digital watermarks sent from the center side and free content such as one-seg broadcasting for mobile terrestrial digital broadcasting.

FIG. 27 shows a flow of monitoring and operation of digital watermark embedding information.
The microprocessor 301 performs personal authentication based on an input signal from the keyboard 11 or the keyboard 21. For example, when the mobile phone or the input / output device is turned on, the personal identification number, password, contact IC card, non-contact IC card or biometric authentication such as voice, fingerprint, face, iris, etc. is used to obtain personal authentication information, and the ROM 312 To remember. When an execution request for a program that handles moving images or audio signals is made, the microprocessor 301 performs wireless communication with the center side and receives moving images or audio signals. The microprocessor 301 monitors whether a digital watermark is embedded in the moving image or audio signal, and if not embedded, reproduces the moving image or audio.

  When the digital watermark is embedded, the microprocessor 301 requests the personal authentication information and compares the obtained information with the already stored personal authentication information. If they match, the video and audio are played normally as a successful identity verification. If they do not match, an unsuccessful abnormal video or audio is played back as a failure of identity verification.

  As a result, copyright protection and a billing system can be constructed. For example, paid movies can be distributed over the network. If the contactless IC card used for personal authentication is a prepaid electronic money card, playback and settlement can be performed at the same time, and the convenience of the content provider and the user is further enhanced.

  The above is a flow of monitoring and playback of a digital watermark embedded video and audio in the so-called streaming mode when video and audio signals are received immediately. The video and audio are temporarily stored with the digital watermark embedded in the ROM 312 and then played back later. It can also be applied to so-called accumulation type reproduction.

  A fifth application example of the computer system configured as described above is to manage permission and prohibition of connection of external devices to the input / output device on the center side.

FIG. 28 shows a flow of external device connection monitoring.
When an external device connection request is made from the program, the microprocessor 301 performs wireless communication with the center side, receives the permission / prohibition state of the external device connection, and stores them in the ROM 312.

  There are two types of received statuses. The first status indicates permission / prohibition of external device connection, “1” indicates permission, and “0” indicates prohibition. The second state indicates whether or not the state 1 can be changed, “1” indicates that the state can be changed, and “0” indicates that the state cannot be changed. However, changes can only be made if authorized.

  The microprocessor 301 discriminates the state 1 and if it is “1”, permits the connection of the external device. If “0”, state 2 is determined. If the state 2 is “1”, the state 1 can be changed. If the state 2 is “0”, the change is impossible, and the connection of the external device is prohibited. To change state 1, you need to check if you are authorized. When the state 2 is “1”, the microprocessor 301 requests the personal authentication information and compares it with the pre-stored personal authentication information. If they match, the identity verification is successful, the status 1 can be changed, "0" is changed to "1", and external device connection is permitted. If they do not match, identity verification has failed and connection to an external device is prohibited.

As a result, for all external device connection requests, the status 1 is set to “0”, and after authentication, “1” is granted and the connection is permitted. Downloading to an external storage device can be prevented. In response to all external device connection requests, the status 1 is set to "0" and the status 2 is set to "0" to prohibit all external devices from being connected, and a thin client without an external storage device (thin client ) It is possible to build a system The above is an example of permitting or prohibiting connection of external devices all at once, but by subdividing state 1 and state 2, connection is permitted for printers and connection for DVDs is prohibited It becomes possible to manage from the center side in detail.

  A sixth application example of the computer system configured as described above is management of lock and release of some or all functions of a mobile phone or an input / output device. The user switches between enabling or disabling operation of some or all functions of the mobile phone or input / output device using the keyboard of the mobile phone or input / output device (hereinafter referred to as local lock), and changing the status as necessary. It is managed so that it can be registered at the center side, received from the center as needed, and returned to the original local lock state. Examples of local locks include display locks on the display unit of a mobile phone or input / output device, a phone book in a mobile phone or input / output device, a schedule table, an e-mail address, an image file, and a specific confidential information file. There are access locks, external transmission restrictions, access restrictions to specific websites, etc.

  FIG. 29 shows a monitoring flow based on an input signal from the keyboard 11 or the keyboard 21. If n local lock signals are included in the signal from the keyboard 11 or the keyboard 21, the microprocessor 301 stores the states 1 to n in the ROM 312 and registers by performing wireless communication with the center side. When an event occurs, the microprocessor 301 performs wireless communication with the center side, receives the registered local lock states 1 to n, and returns them to the ROM 312. An event is a power-on / off of a mobile phone or an input / output device, execution of a local lock state operation program, execution of another local lock by the keyboard 11 or the keyboard 21, and return to the original local lock state. Etc.

  This locks the display when the user leaves the computer system while using the computer system, prohibits access to important files when lending to others, or operates the mobile phone even if it is accidentally lost It is possible to make the setting impossible by the user based on the user's own intention.

A seventh application example of the computer system configured as described above is management of lock and release of some or all functions of a mobile phone or an input / output device when an event occurs.
Here event is
・ Receiving signals from the center side to lock and release some or all functions of mobile phones or input / output devices (hereinafter referred to as center lock)
・ Opening / closing of mobile phone display ・ Opening / closing of input / output device display ・ Removing / attaching interface cable between mobile phone and input / output device
・ I / O device power ON / OFF
This refers to an event that causes program execution interruption.

  When this event occurs, the abnormal state is stored according to each event, and the execution of the program is interrupted. When the event returns to normal, the user authentication is performed, and when the user identification is successful, the state is returned to the normal state and the execution of the program is resumed. When a plurality of events occur simultaneously, a plurality of states can be processed at the same time, and some functions can continue to operate depending on the event.

  FIG. 30 shows an event state monitoring flow. Based on an input signal from the keyboard 11 or the keyboard 21, the microprocessor 301 performs wireless communication for receiving the center lock state, and reading of the state for checking the state of the mobile phone and the input / output device. Based on the result, center lock, opening / closing of mobile phone display, opening / closing of input / output device display, removal of interface cable between mobile phone and input / output device, mobile phone power ON / OFF, input / output device power ON, The state corresponding to each of OFF is defined as event states 1 to n, and each event state is "1" if the computer system is operable and locked, or "0" if the computer system is locked or abnormal. Store in ROM312.

  Prior to execution of a program executed by the microprocessor 301 based on an input signal from the keyboard 11 or the keyboard 21, the microprocessor 301 discriminates event states 1 to n. Suspend execution. If all are “1” in the normal state, the microprocessor 301 executes the program. In this figure, the state m is “0” and the execution of the program is interrupted. When an event occurs during execution, the microprocessor 301 determines which event has occurred. Although details of the determination are not shown, the determination is made using an interrupt address for the microprocessor 301 or the like. The figure shows that the state k has occurred, the execution of the program is interrupted, and the corresponding state is stored as “0”. When the event returns to normal, the microprocessor 301 requests the personal authentication information and compares it with the pre-stored personal authentication information. If they match, the identity verification is successful, and the microprocessor 301 changes “0” to “1” in the state k or the state m, and resumes execution of the program. If they do not match, identity verification has failed and program execution will not resume.

This makes it possible to finely manage execution, interruption, and resumption of the computer system program for each event. Since restarting requires identity verification, it can help improve security. For example, if you leave your seat while an important program is running, you can prevent the other person from resuming the program by interrupting the program execution by opening / closing the mobile phone display or opening / closing the input / output device display. can do. In another example, when the computer system storing the specific confidential information is accidentally lost, the information can be prevented from being lost by contacting the center with another mobile phone when the computer system is noticed and locking the center.
The states 1 to n are also referred to from other programs, other mobile phones, other input / output devices, or the center side, and are used at the time of program execution request, security management, and the like.

  In the computer system configured as described above, the role of the cellular phone ROM 312 can be replaced by a rewritable ROM of the input / output device such as a ROM 703 formed of a flash memory. The identity authentication may be performed from the input / output device.
