Description

A device for serving both as a common computer and a certain program only computer}

The present invention relates to a computer that can be used as a general computer or a specific program dedicated device, in particular a word processor dedicated by using a switch operation by using two or more microprocessors, a main memory device, a secondary memory device, and the like.

In addition, in the present invention, a plurality of microprocessors, a plurality of main memory devices, a plurality of auxiliary memory devices, and the like are used, so that the other circuit can be used as a specific program dedicated device while one circuit is booted, Provides a device that can use the general computer circuit. In addition, the two circuits may be mutually checked.

The effect of the present invention is not only to speed up booting like a specific program, especially a word processor, but also to automatically turn off the power switch without the hassle of saving data or terminating the program. In addition, even if a booting program is damaged, a certain program does not delay booting or prevent booting.

A separate device can be booted by a word processor dedicated device and other circuits, and even mutually checked.

The prior art in this field is as follows. There is a word processor dedicated to speeding up booting. The word processor only stores programs in the ROM and saves the data to disk so that users can quickly boot and use the data immediately. In addition, when the power failure is detected, they are stored in the hard disk as it is, and the power is cut off and the stored information is displayed as it is. The problem with the word processor is that its use is limited compared to its price. So it has not been used well lately.

There is a suspension mode, or a suspend disk mode (Hibernation mode), which is recently used in notebook computers in the storage of data in use, the termination of a program, and a power off technique. When a power failure is detected, they are used to store the information in the memory as it is, the power is cut off, and the information stored at boot is displayed. The problem with the suspend disk mode (Hibernation mode) is that errors such as collision of information stored on the disk when returning are likely to occur. This is because the power is stored in an unstable state and the program you are using does not fit properly with other software.

Compared to my patent application, (A computer that can simplify booting and shutdown), (A computer that can easily boot and shut down) uses only a plurality of non-volatile memory or divides the same non-volatile memory. In the present invention, a microprocessor or other component configuration may be relatively single, and a connection of a ROM may be selected. The present invention may have a plurality of microprocessors, a plurality of component configurations, and a plurality of operating systems. There is this. The advantages that come with it are that you can cross-check your system and boot from one side while the other is in use. If the present invention has a drawback than a computer that can simply boot and shut down, the method is more complicated and uses more parts, resulting in heavier weight and expensive price.

The present invention relates to a computer that can be used as a general computer by switching operations by using two or more microprocessors, a main memory device, an auxiliary memory device, or a specific program dedicated device, for example, a word processor dedicated device or an Excel dedicated device. .

The effect of the present invention is not only to speed up the booting of a particular program, especially a word processor, but also to automatically turn off the power switch without the hassle of saving the data in use or terminating the program. In addition, even if a booting program is damaged, a certain program does not delay booting or prevent booting.

A separate device can be booted by a specific program dedicated device and a different circuit, and even mutual inspection can be performed.

In the technique of storing the data in use, terminating the program and shutting off the power, interrupts are generated by separate switches, and the user interrupt is prepared in advance in the ROM's interrupt vector table under the control of the microprocessor. After that, the program is terminated and the power is automatically cut off.

The difference from the prior art of this invention is as follows. First of all, compared to a specific program dedicated device, especially a word processor dedicated program, it is a program that is used much like a word processor. It has the advantage of being able to use a specific program dedicated device as quickly and simply as possible. In addition, there is an advantage that the data can be saved, the program can be terminated, and the power can be shut off with one switch.

Comparing the present invention with the suspend mode, or the suspended disk mode (Hibernation mode), which is commonly used in notebook computers, is as follows. When a power failure is detected, they are used to store the information in the memory as it is, the power is cut off, and the information stored at boot is displayed. The problem with the suspend disk mode (Hibernation mode) is that errors such as collision of information stored on the disk when returning are likely to occur. This is because the power is stored in an unstable state and the program you are using does not fit properly with other software. In the present invention, the switch is operated to intentionally generate an interrupt, and the interrupt is to automatically save the data in use and terminate the program as well as shut down the power supply. In this case, the advantage is that the operation can be simplified, and the suspend disk mode is provided by pre-integrating a program that automatically stores data in a nonvolatile memory used like a specific program exclusively, shuts down the program automatically, and automatically shuts off the power. This prevents frequent corruption of the program or data in use due to a crash at the time of returning in Hibernation mode.

The saving of the data in use, the termination of the program, and the interruption of the power supply are not automatically made by the switch, but by the selection of the keyboard. The program is terminated after the active data is saved and then interrupted by the software change of the circuit. In this case, the power of the relay or the GTO thyristor as shown in FIG. 2 or FIG. 3 may be cut off.

Unlike my own patent application, a computer that can simplify booting and shutdown, the present invention is characterized by having a plurality of microprocessors, a plurality of component configurations, and a plurality of operating systems. The advantages that come with it are that you can cross-check your system and boot from one side while the other is in use.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an embodiment of the present invention. The power source of the power supply device 10 is connected to the switch device 20. The switch device 20 may include a mechanical switch as well as a triac, thyristor-diode.bridge, or relay circuit, and may be connected and used under the control of a microprocessor. The switch device is configured to selectively connect either (1) or (2). If switch (1) is connected, ROM 1 (71) with built-in program that can be used as a specific program exclusive device, timer 1 (81) including free operation timer with multiple channels, and microprocessor 1 (91) ), Number and floating point processor FPU1 (101), interrupt controller 1 (111), RAM 1 (121), serial interface SIO 1 (131), hard disk drive controller HDC 1 (141) and hard disk drive HDD 1 ( 143), real-time clock RTC 1 (151) that displays the current elapsed time, DMAC 1 (161), a DMA controller that allows high-speed data transfer between memories without the presence of a microprocessor, and expansion PORT 1 (connected to LEDs). 171, ROM 3 (73), etc. are connected to the power source and operated.

If switch (2) is connected, ROM 2 (72), timer 2 (82), microprocessor 2 (92), FPU2 (102), and interrupt controller 2 (112) with built-in programs for use as a general computer , RAM 2 (122), SIO 2 (132), HDC 2 (142) and HDD 2 (144), RTC 2 (152), DMAC 2 (162), LED PORT 2 (172), etc. It works.

Keyboard Controller KBC (31), Keyboard KB (32), Floppy Disk Drive FDC (51), Floppy Disk Drive FDD (52), Parallel Interface PIO (61), Parallel Interface, Separate Processor, Main Memory and Printer The printer device 62 having the driver and the head, the VGAC 41 controlling the VGA, the monitor screen or the LCD 42, etc., are automatically connected to the switch side connected to the power source among the (1) switch or (2) switch. As a result, the side connected to the power source operates the keyboard and the screen is displayed on the monitor screen or LCD.

Even if power is connected to (1) and (1) is working, you can boot the other with 180 spare power. When the switch (20) is connected by the switch device 20, the (2) side can also be booted. However, the (2) side does not appear on the monitor screen or LCD 42 at this time. With the switch (6) connected, disconnect the switch (1) and connect the switch (2) to display the boot status. Likewise, even if the power is connected to the (2) side and the (2) side operates, the other side can be booted with the reserve power 180. When the switch (5) is connected by the switch device 20, the (1) side can also be booted. However, the (1) side does not appear on the monitor screen or LCD 42 at this time. With the switch (5) connected, disconnect the switch (2) and connect the switch (1).

When the switch device 20 turns on and off the switch (1) at the same time, the switch (3) is connected to a power source to operate the timer 3 (191) and generate an interrupt with the interrupt generator 201. The interrupt is confirmed, and the data in use by the user interrupts pre-written in the interrupt vector table of the ROM 1 71 is stored, and the timer is cut off after a certain time so that the power is completely cut off after a while. The timer can be connected to the power supply instantaneously when voltage is applied and the time-return type timer and off / relay timer that turn off the power after a certain period of time after the power is removed. Switch (3) is automatically cut off when the user reconnects power to switch (1).

When the switch device 20 turns on and off the switch (2) at the same time, the switch (4) is connected to a power source to operate the timer 4 (192) and generate an interrupt with the interrupt generator 202. Is saved and the timer is cut off after a certain time, so the power is completely cut off after a while. The timer can be connected to the power supply instantaneously when voltage is applied and the time-return type timer and off / relay timer that turn off the power after a certain period of time after the power is removed. Switch (4) is automatically cut off when user reconnects power to switch (2).

The switch 5 and the switch 6 are switches for connecting with a spare power source. Redundant power can be used if there is a problem with the power supply, and in the case of notebook computers, it can be matched with the power supply. The switch 7 is a switch connecting the ROM 3 (73). When using ROM3 (73) as a nonvolatile memory capable of storing such as EPROM (Erasable and Programmable ROM), Fresh EPROM, or EEPROM (Electrically Erasable and Programmable ROM) Fe RAM, the switch (7) can be connected and used. The booting program is built in the 73 and can be used for the connection of the switch 5 and the connection of the switch 7. The switch 7 is composed of a triac, thyristor-diode.bridge, or relay circuit as well as a mechanical switch in a state of being connected to a (preliminary) power supply, and may be connected and used under the control of a microprocessor.

FIG. 2 is an embodiment using a relay instead of the timer of FIG. When the switch 1 is cut off by the switch device 20, the switch 3 is automatically connected, and an interrupt is generated without operating the relay 193, and data currently being used is stored. After the storing is completed, the relay 1 193 cuts off the power by the microprocessor 1 91. Then, when the switch 1 is operated again, the switch 3 is automatically cut off and returned to its original state. When the switch 2 is cut off by the switch device 20, the switch 4 is automatically connected and the interrupt is generated without operating the relay 2 194. The data currently being used by the user interrupts pre-written in the interrupt vector table are stored and the program is terminated, and the relay 2 194 is turned off by the microprocessor 2 92. After operating the switch (2), the switch (4) is cut off by itself and returns to its original state. Similarly to the case of FIG. 1, in the case of a program to be used as a specific program exclusive device, software that is not overwhelmed by such storage and power cutoff may be provided by the ROM 1 71 under the control of a microprocessor by an interrupt.

3 is an embodiment using a GTO thyristor instead of the relay of FIG. When the switch 1 is cut off by the switch device 20, the switch 3 is automatically connected and an interrupt is generated through the thyristor 195. The interrupt is confirmed by the microprocessor, and the interrupt vector table of the ROM 1 71 is checked. After the data currently being used is stored by the user interrupts written in advance, the program is terminated and the trigger circuit 197 is operated by the microprocessor 1 91 to cut off the power of the thyristor 195. After operating the switch (1), the switch (3) is automatically shut off and returned to its original state, and the thyristor is also restored to its original state. When the switch 2 is cut off, the switch 4 is automatically connected and an interrupt is generated through the thyristor 196 to store data currently being used. After storing, the trigger circuit 198 is operated by the microprocessor 2 92 to cut off the power of the thyristor 196. When the switch is operated afterwards, the switch 4 is automatically disconnected and returned to its original position, and the thyristor is also returned to its original position.

1, 2, and 3, in the case of a program to be used as a specific program dedicated device, software that is not overwhelmed by such interruption of storage and power supply by the control of the microprocessor by an interrupt may be provided in the ROM 1 71. . In order to prevent the program from being saved during power saving and normal program execution, which can be started by the ROM 2 (72), the information being used in the memory is allocated as it is in the suspend disk mode (Hibernation mode). You will need a separate program or a program that can save and restore the saved hibernation area. This may expose the problem of the notebook's existing suspend disk mode, which is the occurrence of crashes and errors on return. Therefore, in order to take advantage of the technical progress of the present invention with respect to the suspend disk mode (Hibernation mode), it may be convenient to close the automatic storage automatic shutdown automatic shutdown device when connected with the switch 2.

If you connect the power by operating the switch by using the program embedded in the ROM, you can have the working place of a specific program dedicated device such as a word processor dedicated. Alternatively, when a specific time is reached by a real-time clock and a timer, the power is turned on by itself, and a program related to the word processor may indicate a working position of the word processor. The ROM 1 (71) is a ROM in which a program for use as a specific program is located, and may be booted in preference to the ROM 3 (73) used as a general program.

ROM 1 (71) consists of non-volatile memory, such as erasable and programmable ROM (EPROM), fresh EPROM, or electrically erasable and programmable ROM (EEPROM) Fe RAM, allowing all new specific programs, or startup and disk connections and connections. Can be used as a new specific program dedicated device or replaced with another specific program dedicated device, and a separate device (e.g. PROM burner) Can be installed internally. In this case, you can embed a program that can automatically save the data in use, terminate the program, and shut down the power. This prevents data or programs from being damaged, unlike the suspend mode or the suspend disk mode of recent notebook computers.

If necessary, the general program can be used by the ROM 3 73 in a hardware or software manner. Also, a program or data driven by the ROM 1 (71) and a program or data connected by the ROM 2 (72) may be embedded in the ROM 3 (73) or another ROM.

The ROM 3 (73) can be configured with nonvolatile memory such as erasable and programmable ROM (EPROM), fresh EPROM, or electrically erasable and programmable ROM (EEPROM) Fe RAM to store all or part of the data in use. When saving, the remaining active data can be saved in the designated area of the hard disk. In addition, if necessary, the general program may be booted by the ROM 3 (73) by a hardware method or a software method.

Interrupt generators use common chips and circuits. The interrupt generated by this interrupt generator causes the microprocessor to acknowledge the interrupt and save the current progress by the user interrupts pre-written in the ROM's interrupt vector table and terminate the program. When using a timer circuit, the timer is automatically turned off after sufficient time for storing and ending. The switch 3 or switch 4 may use a mechanical switch, may be replaced by a relay or thyristor, and may be operated by changing or selecting a software or hardware circuit by the keyboard.

In the present invention, the backup power supply and the power supply device may be matched. When used as a portable computer, the power supply can be general household electricity and the spare power supply can be a battery.

The devices of the present invention may be a kind of parallel processing computer, and may have the same kind or the same operating system in a memory or a processor. Alternatively, the memory or processor may be configured with CISC or RISC, and may have different operating systems.

The ROM 1 71 and the ROM 2 72 may be set to two separate regions of the same ROM, and other main memory devices or auxiliary memory devices may be set to two separate regions. In this case, separate circuits and switch devices may be employed.

The devices of the present invention can add additional circuits, chip switches, etc. when used in connection with a computer network, and can develop software suitable for the purpose. For example, different computer programs for ROM 1 (71) and programs for ROM 2 (72) are installed, and the programs that mediate both are installed in ROM 3 (73) to effectively use the computer networks led by separate programs. You can do that.

The drawings are only examples, and anyone who is knowledgeable in electronic circuits can design the concept of the present invention into various circuits.

The effect of the present invention relates to a computer that can be used as a general computer by using a switch operation by using two or more microprocessors, a main memory device, an auxiliary memory device, or a specific program dedicated device, in particular a word processor dedicated device.

Word processor dedicated devices can be used as word processors at the touch of a switch. Simple learning was once widely used. However, it is rarely used now due to limited functions compared to laptops and general computers and high price compared to using functions. Aside from being easy to learn, the advantage of word processors is that it takes a short time to boot, save data in use, and exit the program. Instead, it cannot be used for various functions like a normal computer. Accordingly, the present invention is to provide a computer device having the functions of a general computer while maintaining the advantages of a specific program dedicated device such as a word processor dedicated device. In other words, if one switch is operated, it can be used for various functions like a general computer.If the other switch is used, a specific program comes out as soon as the switch is turned on like a specific program dedicated device such as a word processor dedicated device. Make it easy. However, when switching off the switch, the user can save the data in use, terminate the program, and turn off the power automatically.

In addition, in the present invention, a plurality of microprocessors, a plurality of main memory devices, a plurality of auxiliary memory devices, and the like are used, so that the other circuit can be used as a specific program dedicated device while one circuit is booted, Provides a device that can use the general computer circuit. In addition, the two circuits may be mutually checked. The effect of the present invention is that it is possible to turn off the switch without the hassle of saving the data in use, terminating the program, or shutting down the power, as well as fast booting like a specific program, especially a word processor. In addition, even if a booting program is damaged, a certain program does not delay booting or prevent booting. A separate device can be booted by a circuit device used as a specific program dedicated device and another computer circuit device used as a general computer, and even mutual inspection can be performed.
