Description

  The present invention relates to an electronic apparatus including a control unit that can control an operation mode of a calculation unit (CPU: Central Processing Unit).

  2. Description of the Related Art In recent years, electronic devices including portable information terminals have been challenged with a power management mechanism as a countermeasure against increased power consumption and heat generation due to higher performance of a calculation unit (CPU) and multicore.

  Such a power management mechanism has long been equipped with a function to operate in a power saving mode called “suspend” or “hibernation” in order to reduce power consumption when the user does not use the electronic device. The configuration and the configuration having a function of stopping the CPU and other devices themselves have been known, but recently, this is called a degeneration operation, and the CPU frequency and the frequency are dynamically changed during the execution of the CPU. A method of changing the voltage (Dynamic frequency scaling, Dynamic voltage scaling), or reducing the number of operating cores using power gating is used.

  Although such a degeneration operation has the effect of satisfying the reduction in power consumption and heat generation, it is inherently incapable of expressing all the processing capabilities of the CPU, so there is a method for effectively suppressing and controlling the degeneration operation. It has been demanded.

  Thus, as a method for effectively suppressing and controlling the degeneration operation in this way, for example, Patent Document 1 discloses that the performance of the imaging process is increased by increasing the number of clocks of the CPU when shooting with a camera. Patent Document 2 describes increasing the number of CPU clocks triggered by key input.

  However, the configurations disclosed in Patent Documents 1 and 2 all depend on specific hardware such as a camera and a key input device, and the configuration disclosed in Patent Document 1 is only a CPU. Is not configured to increase the number of clocks of the CPU according to this, and the configuration disclosed in Patent Document 2 described above is at a timing at which CPU processing is not particularly necessary. However, there is a problem that the power consumption increases because the number of clocks of the CPU is increased even in the case of the key input.

  In view of such problems, a method using a power management mechanism in an operating system (OS) has been proposed.

  For example, Patent Document 3 discloses a method for changing the CPU processing speed during execution depending on the process status.

  Further, Patent Document 4 discloses a configuration in which, even when an interrupt occurs, the number of clocks of the CPU is increased in the event that an interrupt occurs, so that the interrupt time can be kept within the processing time.

  Patent Document 5 discloses a configuration for increasing the number of clocks of the CPU when the processing does not end within a specific time.

  In addition, conventionally, a launcher that selects a plurality of applications that can be executed in an electronic device including an information portable terminal such as a smartphone having a graphical user interface (GUI) and applications to be started from them. When a user selects an application using the launcher while holding an application with a function (hereinafter referred to as a launcher), if the CPU is performing a degenerate operation at the start timing, it will be “sticky” and “unresponsive” The operation feeling was infringed.

  In recent years, with the enhancement of GUI functions, the launcher can be restored after the application is finished, temporarily holding information in the volatile memory or nonvolatile memory at the same time as the application startup, and the user interface The control of (U / I) input / output is delegated to the application, and the launcher itself tends to have a function of inactivation, and the processing amount accompanying the inactivation of the launcher also tends to increase.

  Such processing performed when the launcher is inactivated is one cause of lowering usability when the CPU is in a degenerate operation.

  Therefore, it has been proposed that the launcher receives an event for selecting an icon and performs CPU high fixation (degeneration suppression) processing from the launcher to speed up application startup and improve poor play and reaction. ing.

JP 2010-166607 A (published July 29, 2010) JP 2010-39791 A (published February 18, 2010) Japanese Patent No. 4123640 (released July 23, 2008) JP 2006-235907 A (published September 7, 2006) JP 2002-304232 A (published on October 18, 2002)

  However, the configuration linked to the function of the OS as disclosed in the above Patent Documents 3 to 5 has the following problems although a certain effect can be obtained.

  In the configuration described in Patent Document 3, since it is not known in advance how much processing the application requires, it is impossible to determine whether the number of clocks of the CPU can be increased.

  In addition, the configuration described in Patent Document 4 has a limited range because only limited processing (interrupt processing) occurs, and a complex processing called activation because a single interrupt processing delays the operation. Not suitable for.

  The configuration described in Patent Document 5 is a configuration in which the CPU clock number is increased after a processing delay occurs. Therefore, when the delay occurs, the CPU clock number increasing process that is performed for the first time is performed. There is a problem in that the user does not experience the speed because the processing is delayed until the time for confirming the occurrence of the delay.

  Also, in the above-described launcher, in the method of receiving an event for selecting an icon and performing high fixation (degeneration suppression) processing of the CPU from the launcher, the application activation speed is increased, and the poorness of the play and response is improved. Requires a module for performing CPU high fixing (degeneration suppression) processing or issuing a request to the launcher in advance. In addition, since the launcher is related to the resource control of the CPU, it needs to be trusted from the flat form in advance in consideration of security. For example, Android is managed by permission or signature.

  The present invention has been made in view of the above problems, and its purpose is to efficiently control the degeneration operation of the arithmetic unit provided in the electronic device according to the user's input operation on the input surface, It is an object of the present invention to provide an electronic device that enables efficient power consumption without impairing the user's feeling of operation.

  In order to solve the above problems, an electronic device according to the present invention includes a detection unit that detects a user input operation on an input surface, and is driven according to the user input operation detected by the detection unit. The calculation unit includes a normal operation mode and a low power consumption operation mode in which the power consumption is lower than that of the normal operation mode, and the input operation detected by the detection unit is determined by the calculation unit. In the case of the first type of input operation that needs to maintain the above performance, after the user's input operation is completed, the calculation unit is operated in the normal operation mode for a predetermined period and detected by the detection unit. When the input operation performed by the user is a second type of input operation that does not require the calculation unit to maintain a performance exceeding a predetermined level, after the user input operation is completed, the calculation unit is operated for a predetermined period. Low power consumption It is characterized by comprising a control unit for operating in dynamic mode.

  According to the above configuration, the calculation unit needs to maintain a predetermined performance or higher based on a user input operation on the input surface without depending on an application or an application having a launcher function (hereinafter referred to as a launcher). It is determined whether it is a type of input operation or a second type of input operation that does not require the calculation unit to maintain a performance of a predetermined level or more. A control unit is provided that operates the calculation unit in the normal operation mode for a predetermined period and operates the calculation unit in the low power consumption operation mode for a predetermined period when the input operation is the second type. ing.

  Electronic device launchers, such as smartphones, tend to be customized, such as downloading and using favorite ones when the user's literacy goes up. In the configuration in which the calculation unit is driven from the launcher in the normal operation mode, if the launcher changes, the calculation unit cannot be controlled.

  On the other hand, according to the above configuration, the control unit makes a determination based on the user's input operation on the input surface and efficiently controls the calculation unit, so even if the type of the launcher changes (to the type of the launcher) Regardless of this, it is possible to realize an electronic device that can speed up the activation of an application and efficiently consume power without impairing the user's feeling of operation.

  Moreover, according to the said structure, since the said control part performs determination based on the user's input operation with respect to an input surface, it can control a calculating part with high precision according to the condition. Therefore, an electronic device that can be driven with lower power consumption can be realized.

  In the electronic device of the present invention, the arithmetic unit operates in the normal operation mode when a degeneration suppression signal is transmitted from the control unit, and when the degeneration suppression signal is not transmitted from the control unit, It may be configured to operate in the low power consumption operation mode.

  According to the above configuration, since the control unit can control the operation mode of the calculation unit depending on whether or not to send a degeneration suppression signal to the calculation unit, the configuration of the control unit is compared. Can be simplified.

  In the electronic device of the present invention, the user's input operation includes a touch-down operation in which the user's input means is in contact with the input surface, and a touch move operation in which the user's input means is in contact with the input surface. And a touch-up operation in which the user's input means moves away from the input surface, and the user's input operation is completed by the touch-up operation, and at the time of the touch-up operation, the user's input operation is completed. It may be configured to determine whether the input operation is the first type input operation or the second type input operation.

  According to the above configuration, it is possible to realize an electronic device that can control the calculation unit with high accuracy and can be driven with lower power consumption in accordance with a user input operation.

  In the electronic device of the present invention, the control unit performs the input operation of the user when the input means of the user is in contact with the input surface more than a predetermined number of times within a predetermined period. It is preferable to determine the operation.

  In the electronic device according to the aspect of the invention, when the control unit includes an operation in which the input unit of the user makes contact with the input surface for a predetermined time or more, the control unit performs the input operation of the user as the second type of input operation. It is preferable to determine.

  In the electronic device according to the aspect of the invention, the amount of movement of the input unit from the state in which the user input unit is in contact with the input surface to the non-contact state is greater than or equal to a predetermined amount. In this case, it is preferable that the input operation of the user is determined as the second type of input operation.

  In the electronic device of the present invention, the control unit may change the user's input operation to the second type of input operation when the user's input means is in contact with the input surface more than once per second. Is preferably determined.

  In the electronic device of the present invention, when the user input means includes an operation of contacting the input surface for 300 milliseconds or more, the control unit performs the user input operation as the second type input operation. Is preferably determined.

  In the electronic device according to the aspect of the invention, the control unit may determine the amount of movement of the input unit until the input unit of the user is in contact with the input surface until the non-contact state is reached. When the width in one direction with the surface in contact with the surface is 0.1 times or more, it is preferable that the input operation by the user is determined as the second type input operation.

  According to the configuration, based on the input operation of the user, the control unit determines that the calculation unit does not need to maintain a performance exceeding a predetermined level (when any of the above conditions is satisfied). ), The operation unit is operated in the low power consumption operation mode for a predetermined period.

  Therefore, an electronic device that can be driven with low power consumption can be realized.

  In the electronic device according to the aspect of the invention, the control unit may include a first condition that the user's input operation makes contact with the input surface less than a predetermined number of times within a predetermined period; The second condition that the input operation does not include an operation in which the input means is in contact with the input surface for a predetermined time or more, and the input operation of the user is in a non-contact state from a state in which the input means is in contact with the input surface. If either of the third conditions that the amount of movement of the input means until it becomes less than the predetermined amount is satisfied, the user's input operation is changed to the first type of input operation. Is preferably determined.

  In the electronic device of the present invention, when the fourth input condition that the user input operation is performed by one input unit is further satisfied, the user input operation is determined as the first type input operation. It may be configured to.

  According to the configuration, based on the input operation of the user, the control unit determines that the calculation unit needs to maintain a performance exceeding a predetermined level (from the first condition to the third condition). When any of the conditions are satisfied, or when any of the first condition to the fourth condition is satisfied), the calculation unit is operated in the normal operation mode for a predetermined period. ing.

  As described above, since the condition for operating the calculation unit in the normal operation mode is set more severely than the condition for operating the calculation unit in the low power consumption operation mode, the electronic device that can be driven with low power consumption. Can be realized.

  In the electronic device according to the aspect of the invention, the control unit may perform the user input operation following the user input operation for a predetermined period when the user input operation does not satisfy the first condition. Even when any of the conditions from the first condition to the third condition is satisfied, it is preferable to determine that the user input operation following the user input operation is the second type input operation.

  According to the above configuration, when it is determined that the input operation of the user is, for example, an input operation such as character input, the user during the predetermined period is considered in consideration of various input operations in the character input process. The input operation is determined as a character input process.

  Therefore, it is possible to realize an electronic device that can control the arithmetic unit with high accuracy according to the input operation of the user and can be driven with low power consumption.

  In the electronic device according to the present invention, the control unit may be configured to control the user's input operation during a predetermined period when the input operation of the user includes contact with a specific area including the input surface of the user. The configuration may be such that all the user input operations following the input operation are determined as the first type input operation.

  According to the said structure, the said calculating part can be operated by the said normal operation mode by the said user's selection as needed.

  The electronic device of the present invention may include a portable power source.

  Since the electronic device of the present invention is an electronic device that can be driven with low power consumption, it can be more suitably used when a portable power source is provided as a power source.

  As described above, the electronic device of the present invention includes a calculation unit including a normal operation mode and a low power consumption operation mode in which power consumption is lower than that of the normal operation mode, and a user input detected by the detection unit. When the operation is the first type of input operation that requires the calculation unit to maintain a performance exceeding a predetermined level, after the user input operation is completed, the calculation unit is kept in the normal operation mode for a predetermined period. When the user's input operation detected by the detection unit is a second type of input operation that does not require the calculation unit to maintain a performance exceeding a predetermined level, after the user's input operation is completed, And a control unit that operates the arithmetic unit in the low power consumption operation mode for a predetermined period.

  Therefore, it is possible to efficiently control the degeneracy operation of the arithmetic unit provided in the electronic device according to the user's input operation on the input surface, and to efficiently consume power without impairing the user's operational feeling. It is possible to realize an electronic device that makes it possible.

  In the following embodiments, a smartphone as an information portable terminal will be described as an example of an electronic device. However, the present invention is not limited to this, and a tablet terminal, a portable personal computer, etc. The electronic device may be, for example, a monitor or a television receiver in addition to the portable electronic device.

Embodiments of the present invention will be described in detail with reference to FIGS.
(Smartphone overview)
FIG. 1 is a block diagram illustrating a main configuration of the smartphone 8 according to the present embodiment.

  Hereinafter, based on FIG. 1, the outline | summary of the smart phone 8 is demonstrated.

  The smartphone 8 includes a touch panel 1 as an input surface, a touch panel driver 2 for driving the touch panel 1, and a touch panel control unit (touch farm) 3 for controlling the touch panel driver 2.

  As illustrated, the touch panel 1, the touch panel driver 2, and the touch panel control unit 3 form a touch panel module (detection unit) 4 that detects a user input operation on the touch panel 1 that is an input surface. .

  Then, the smartphone 8 is driven in accordance with a user input operation detected by the touch panel module 4.

  The control unit (event determination unit) 5 controls an operation mode of a calculation unit (CPU) 6 including an application execution unit based on a user input operation detected by the touch panel module 4.

  The calculation unit 6 has a degeneration operation function, and can be operated in a normal operation mode and a low power consumption operation mode (degeneration operation mode) in which power consumption is smaller than that in the normal operation mode.

  Note that the low power consumption operation mode (degenerate operation mode) means that the power consumption is reduced by stopping some functions included in the calculation unit 6 or changing the frequency or voltage at which the calculation unit 6 operates. The normal operation mode refers to an operation mode that is not a low power consumption operation mode (degenerate operation mode). In the normal operation mode, since the processing speed is increased, there is no infringement of operational feelings such as “mottle” and “poor reaction”, but power consumption is increased.

  In addition, when the degeneration suppression signal is transmitted from the control unit 5 and the degeneration suppression flag of the calculation unit 6 is ON, the calculation unit 6 is operated in the normal operation mode, and the degeneration suppression signal is transmitted from the control unit 5. Instead, when the degeneration suppression flag of the calculation unit 6 is OFF, the operation is performed in the low power consumption operation mode (degeneration operation mode).

  The smartphone 8 includes, for example, a liquid crystal display panel, an organic EL display panel, and a drive circuit thereof as the display unit 7 for performing display.

  Then, the calculation unit 6 controls the touch panel control unit 3 and the drive circuit in the display unit 7.

  FIG. 2 is a diagram illustrating an appearance of the smartphone 8.

  As illustrated in FIG. 2A, the smartphone 8 includes an input unit that is formed integrally with the touch panel 1 and the display unit 7 and a power switch 9.

  Then, as shown in FIG. 2B, the user touches the input unit formed integrally with the touch panel 1 and the display unit 7 by using the input unit 11 (for example, a hand), and it corresponds. The position icon 10 is selected, and the calculation unit 6 executes a process specified by the icon (for example, a process of starting an application specified by the icon).

  Then, as shown in the figure, when the user touches the specific region R1 in the input unit, the control unit 5 drives the calculation unit 6 in the normal operation mode for a predetermined period. .

  In the present embodiment, the 48-dot pixel area of the display unit 7 located at the lower part of the touch panel is set as the specific area R1.

  In the present embodiment, the case where the specific region R1 is provided in the input unit has been described as an example. However, the present invention is not limited to this, and home buttons and back buttons often used for the smartphone 8 are provided. When the area to be arranged is clicked, the application is expected to be started next, so that the calculation unit 6 may be driven in the normal operation mode for a predetermined period.

  And although not shown in figure, the smart phone 8 is equipped with the portable power supply.

  In the present embodiment, the control unit 5 is provided separately from the touch panel module 4 and the calculation unit 6. However, the present invention is not limited to this, and the control unit 5 can be used in the touch panel module 4 or in the calculation. It may be provided in the part 6.

  Hereinafter, based on FIG. 3 to FIG. 6, how the operation mode of the calculation unit (CPU) 6 including the application execution unit is set based on the user input operation detected by the touch panel module 4 performed by the control unit 5. The control will be described.

  FIG. 3 shows a flowchart for classifying user touch event types performed by the control unit 5 provided in the smartphone 8.

  As shown in the figure, the control unit 5 starts an event determination process (S1), and receives event information including coordinates, pressing pressure, area, event time, and the like from the touch panel driver (S2). Then, based on the received event information, the events are classified by type (S3), and are classified into a touchdown event (S4), a touch move event (S5), and a touchup event (S6).

  FIG. 4 shows a process flowchart in the case of being classified as a touchdown event (S4).

  As shown in the figure, after the activation of the smartphone 8 terminal, in the step (S7) for confirming whether it is the first event, if it is determined that the event is the first event, the size acquisition of the touch panel and the user's The amount of movement for the click determination for determining how far the input means has moved is regarded as a click operation, and the degeneration suppression flag of the calculation unit (CPU) 6 are turned off (S8).

  Then, the time and coordinates of the touchdown event are held (S9), the touch event is given to the event time and the application is notified (S10), and the event processing is terminated (S11).

  On the other hand, if it is determined in step (S7) that the event is the first event after activation of the smartphone 8 terminal, it is determined that the event is not the first event, the degeneration suppression flag of the calculation unit (CPU) 6 is ON. Or OFF (S12).

  When the degeneration suppression flag of the calculation unit (CPU) 6 is OFF, the time and coordinates of the touchdown event are held (S9), the event time is given to the touch event, and the application is notified (S10). The process is terminated (S11).

  In the step (S12) for checking whether the degeneration suppression flag of the calculation unit (CPU) 6 is ON or OFF, if the degeneration suppression flag of the calculation unit (CPU) 6 is ON, degeneration suppression is performed. The process proceeds to a step (S13) for confirming whether a predetermined time or more (for example, 2 minutes) has elapsed since the flag is turned on, and if a certain time or more has not passed since the degeneration suppression flag is turned on in the calculation unit (CPU) 6, touch The time and coordinates of the down event are held (S9), the touch event is given to the event time, and the application is notified (S10), and the event processing is terminated (S11).

  On the other hand, if a certain period of time has elapsed since the degeneration suppression flag ON of the calculation unit (CPU) 6 has elapsed, the process proceeds to step (S14) where the degeneration suppression flag of the calculation unit (CPU) 6 is turned OFF, and the degeneration suppression flag is set. After being turned off, the time and coordinates of the touchdown event are held (S9), the event time is given to the touch event and notified to the application (S10), and the event processing is ended (S11).

  As described above, the control unit 5 does not perform control to drive the calculation unit 6 in the low power consumption operation mode (degenerate operation mode) depending on a touchdown event that means the start of the user's input operation. .

  In order to turn on the degeneration suppression flag of the calculation unit (CPU) 6, a degeneration suppression signal is sent from the control unit 5, and to turn off the degeneration suppression flag of the calculation unit (CPU) 6, the control unit 5. It is only necessary to stop sending the degeneration suppression signal from.

  FIG. 5 shows a processing flowchart in the case of being classified as a touch move event (S5).

  As shown in the figure, when the touch event is classified as a touch move event (S5), the touch event is given to the event time and the application is notified (S10), and the event process is terminated (S11).

  As described above, the control unit 5 does not perform control to drive the calculation unit 6 in the low power consumption operation mode (degenerate operation mode) depending on a touch move event meaning that the user is performing an input operation. ing.

  FIG. 6 shows a process flowchart in the case of being classified as a touch-up event (S6).

  As shown in the figure, when the touch event is classified as a touch-up event (S6), a step of confirming whether the degeneration suppression flag of the calculation unit (CPU) 6 is ON or OFF (S15). If the degeneration suppression flag of the calculation unit (CPU) 6 is ON, the process proceeds to step (S16) for confirming whether a predetermined time or longer (for example, 2 minutes) has elapsed since the degeneration suppression flag is ON. If the time has not elapsed, the touch event is given to the event time and the application is notified (S10), and the event process is terminated (S11).

  On the other hand, in the step (S16) for checking whether or not a certain period of time (for example, 2 minutes) has elapsed since the degeneration suppression flag ON of the computing unit (CPU) 6 is reached, The degeneration suppression flag of the CPU 6 is turned off (S17), and the process proceeds to a step (S18) for confirming whether a predetermined time (for example, 1 second) or more has elapsed since the previous CPU control.

  Further, in the step (S15) for confirming whether the degeneration suppression flag of the calculation unit (CPU) 6 is ON or OFF, even when the degeneration suppression flag of the calculation unit (CPU) 6 is OFF, It progresses to the step (S18) which confirms whether fixed time (for example, 1 second) or more has passed since CPU control.

  In step (S18) for confirming whether a predetermined time (for example, 1 second) or more has elapsed since the previous CPU control, it is determined that the predetermined time (for example, 1 second) or more has not elapsed since the previous CPU control. If this occurs, the degeneration suppression flag of the calculation unit (CPU) 6 is turned OFF for a predetermined period (S19), the touch event is given to the event time and the application is notified (S10), and the event process is terminated (S10). S11). As such a case, for example, a user's character input operation etc. can be mentioned as an example.

  Since it is assumed that the user's character input operation continues for a predetermined period, a degeneration suppression flag of the calculation unit (CPU) 6 is turned OFF for a predetermined period (S19).

  On the other hand, in the step (S18) for confirming whether a certain time (for example, 1 second) or more has elapsed since the previous CPU control, it is determined that a certain time (for example, 1 second) or more has elapsed since the previous CPU control. If there is a high possibility that the user's input operation is an application drive request, a step of determining whether the amount of movement from the touchdown to the touchup is smaller than a certain amount (for example, 16 Dot Pixel) (S20) )

  When the movement amount from the touchdown to the touchup is a certain amount or more, it is assumed that the operation is not an application activation but a drag gesture or a screen scroll. While the degeneration suppression flag is OFF, a touch event is given to the event time to notify the application (S10), and the event processing is terminated (S11).

  On the other hand, in the step (S20) of determining whether the amount of movement from the touchdown to the touchup is smaller than a certain amount (for example, 16 Dot Pixel), the amount of movement from the touchdown to the touchup is a certain amount (for example, 16 Dot Pixel). If it is determined that the time is smaller (when there is a high possibility that the user's input operation is an application drive request), whether the time from touchdown to touchup is smaller than a certain time (for example, 30 milliseconds). It progresses to the step (S21) to determine.

  If the time from touchdown to touchup is longer than a certain time (for example, 30 milliseconds), it is determined as a long touch gesture, and it is assumed that the application is uninstalled, not started. Therefore, with the degeneration suppression flag of the calculation unit (CPU) 6 in the OFF state, the touch event is given to the event time and the application is notified (S10), and the event processing is ended (S11).

  On the other hand, when the time from touchdown to touchup is smaller than a certain time (for example, 30 milliseconds) (when the user's input operation is highly likely to be an application drive request), the calculation unit (CPU) 6 The deactivation suppression flag is set to ON, the calculation unit (CPU) 6 is fixed in the normal operation mode for a certain period of time (for example, 10 ms, 20 ms, 40 ms, etc.) and the control of the calculation unit (CPU) 6 is started. Is held (S22). Then, an event time is given to the touch event to notify the application (S10), and the event process is terminated (S11).

  As described above, the control unit 5 controls the operation mode of the calculation unit 6 based on the user's input operation during the touch-up operation.

  In the present embodiment, the above-described steps S18, S20, and S21 are provided as conditions for determining the possibility that the user's input operation is a request for driving the application. However, it is also possible to add a condition for confirming whether this is performed by one input means.

  The present invention can be applied not only to smartphones but also to tablet terminals, personal computers, and other electronic devices.
