Description

  The present invention relates to a technique for performing power control in a system including a processor device.

In current power control, a main processor device that performs processing other than power control is required to minimize the power consumption of various hardware devices (hereinafter also referred to as H / W devices) connected to the processor device. Perform mode setting.
The main processor device needs to have high performance in order to perform the original function processing other than the power control processing, and thus the power consumption of the processor device is often large.
Even when only the power control of the H / W device is performed, it is necessary to operate the main processor device for the power control, and as a result, there is a problem that power consumption is excessively used.

  Moreover, although the structure which adds a dedicated power control part for power control and performs power control is also disclosed, there exists the following subject.

For example, in the technique of Patent Document 1, the processor device needs to perform initialization processing and termination processing of the H / W device.
For this reason, when the initialization processing and termination processing of the H / W device are complicated and time consuming, it is necessary to operate the processor device even when there is actually only waiting processing, and the processor device is eventually operated. The time is increased, and the power consumption during the initialization process and the end process is increased.

In the technique of Patent Document 2, a power control unit that performs power control processing provided separately from the processor device is disclosed. However, when the initialization processing of the H / W device is complicated, the power control unit It is necessary to increase the scale.
Further, since the power control unit constantly monitors the H / W device, the power control unit needs to be constantly operated, and the power consumption of the power control unit increases.

JP 2006-172059 A JP 2000-112585 A

As described above, in the conventional techniques, power control is performed by one dedicated power control unit or main processor device.
Therefore, when the initialization process, termination process, and mode change process of the H / W device are complicated, or when the waiting process becomes long, the time for which the power control unit operates only for the initialization process or the like becomes long. Alternatively, the time for which the processor device operates only for initialization processing or the like becomes long, and power consumption increases.

  The main object of the present invention is to solve such a problem, and the main object is to save power in a system including a processor device.

The setting process execution device according to the present invention is:
A setting processing execution device that is connected to a processor device and a hardware device controlled by the processor device and is capable of switching a power consumption mode between a normal mode and a power saving mode,
At least one of an initialization process after starting power supply to the hardware device and an end process before stopping power supply, a setting process instruction for instructing the hardware device to execute a setting process is sent from the processor device. An instruction receiving unit for receiving,
Setting for executing at least one of a setting process at the initialization process and a setting process at the end process of the hardware device in place of the processor device when the setting processing instruction is received by the instruction receiving unit A processing execution unit,
The power saving mode is maintained until the setting processing instruction is received by the instruction receiving unit. After the setting processing instruction is received by the instruction receiving unit, the mode is changed to the normal mode, and the setting processing execution unit sets the setting processing instruction. When the execution of the process is completed, the mode is shifted to the power saving mode.

In the present invention, at the time of initialization processing or termination processing of the hardware device, the setting processing execution device shifts from the power saving mode to the normal mode, and the setting processing at the time of initialization processing of the hardware device instead of the processor device or The setting process at the end process is executed, and when the execution of the setting process is completed, the mode shifts to the power saving mode.
Therefore, at the time of initialization processing or termination processing of the hardware device, the processor device can be put into the power saving mode, power saving of the processor device can be achieved, and at the time of initialization processing of the hardware device. Alternatively, since the setting process execution device is set to the normal mode only during the end process, the power saving of the setting process execution device can be achieved.

In the following embodiments, a configuration for performing low power consumption control in a battery-driven electronic circuit, a portable terminal, an ASIC (Application Specific Integrated Circuit), or the like that needs to keep the power consumption of the system to a minimum will be described.
In other words, a processor or circuit that performs power control is provided in the product (system), and in addition to the functions and circuits that are subject to power control, the power consumption of the entire system, including the processor and circuit that performs power control, is low. A configuration for keeping the power longer and reducing the power consumption of the entire system will be described.

As a more specific configuration, for example, a simple processor device that performs power control or a mechanism that is set to turn on the power only for the minimum necessary part and time in some blocks in an FPGA (Field Programmable Gate Array) (hereinafter, The simple processor device or the circuit in the FPGA performs processing for the H / W device.
The power control device is smaller than the main processor device and consumes less power.

The main processor device can switch the power consumption mode between the normal mode and the power saving mode.
Further, the power control apparatus can also switch the power consumption mode between the normal mode and the power saving mode.
The normal mode is an operation mode when the main processor device or the power control device operates so as to exhibit a normal function.
The power saving mode is, for example, a sleep mode, which is an operation mode when the main processor device or the power control device operates with a limited function, and consumes less power than the normal mode.
When processing of the main processor device is required, the power control device is turned off (the power control device is set to the power saving mode), and the main processor device performs processing for the H / W device.
When processing of the main processor device is not necessary, the main processor device is turned off (the processor device is set to the power saving mode), and the power control device is turned on (the power control device is set to the normal mode). ), The power control apparatus performs processing for H / W.

With the above method, power control can be performed while reducing power consumption of the entire system.
In addition, setting processing that does not involve waiting time must be executed serially, but setting processing that waits for an event occurrence or time can be multiplexed (parallelized) at the same time, so multiplexing (parallelization) It is possible to shorten the setting processing time.
In the following embodiments, a power control apparatus that shortens the setting time by multiplexing (parallelizing) setting processing will be described.
By shortening the setting time in this way, it is possible to reduce power consumption.

Embodiment 1 FIG.
FIG. 1 shows a system configuration example according to the present embodiment.
The system according to the present embodiment has a configuration in which a CPU (Central Processing Unit) 200, a power control device 100, and a plurality of hardware devices 301 to 303 are connected by a bus 400.
The hardware devices 301 to 303 are also expressed as H / W devices 301 to 303.

In FIG. 1, a CPU 200 is a main processor device.
The CPU 200 can switch the power consumption mode between the power saving mode and the normal mode.
In the following, the CPU 200 performs the initialization process after starting the power supply to the H / W devices 301 to 303, the end process before stopping the power supply to the H / W devices 301 to 303, and the H / W devices 301 to 303. During the mode change process, if the CPU 200 is in the normal mode, the mode shifts to the power saving mode. If the CPU 200 is in the power saving mode, the power saving mode is maintained.
The mode change process of the H / W devices 301 to 303 is a process of switching the power consumption mode in the H / W devices 301 to 303.

The power control apparatus 100 can also switch the power consumption mode between the power saving mode and the normal mode.
The power control apparatus 100 maintains the power saving mode except during initialization processing, termination processing, and mode change processing of the H / W devices 301 to 303, and during initialization processing, termination processing, and mode change processing. Transition from power saving mode to normal mode.
Then, the power control apparatus 100 shifts to the power saving mode after completing the setting process at the initialization process, the setting process at the end process, and the setting process of the mode change process.
The power control apparatus 100 corresponds to an example of a setting process execution apparatus.

  The H / W devices 301 to 303 are hardware to be controlled by the CPU 200 or the power control device 100, respectively.

  FIG. 2 shows an internal configuration example of the power control apparatus 100 according to the present embodiment.

In FIG. 2, the event accumulation management unit 104 receives a setting process instruction from the CPU 200 as an event.
The setting process instruction is a message instructing execution of the setting process at the initialization process of the H / W devices 301 to 303, the setting process at the end process, and the setting process at the mode change process.
The event accumulation management unit 104 accumulates setting processing instructions from the CPU 200.
Further, when the execution of the setting process for the H / W devices 301 to 303 is completed, the event accumulation management unit 104 transmits a setting process execution completion notification for notifying that the execution of the setting process is completed to the CPU 200.
The event accumulation management unit 104 is an example of an instruction reception unit and a notification transmission unit.

The event processing unit 105 can switch the power consumption mode between the normal mode and the power saving mode, maintains the power saving mode until the setting processing instruction is received, and the setting processing instruction is received. After that, shift to normal mode.
As will be described later, when the event processing unit 105 is realized by a program, the event processing unit 105 generates a plurality of events for executing setting processing for the H / W device.
The event generated by the event processing unit 105 is an event that embodies the procedure of setting processing for the H / W device.
The event processing unit 105 may generate a plurality of events for one setting processing instruction.
In addition, the event processing unit 105 schedules the execution order of a plurality of events, and shifts to the power saving mode after the scheduling is completed.
There may or may not be an order constraint between events.
When there is no order restriction, the event processing unit 105 can change the event execution order (event accumulation order).
In the following, an event is an initialization / end / mode change processing request, a processing completion notification, a time-out timeout, a register setting processing execution request, an execution completion notification, an interrupt, or the like.
The event processing unit 105 corresponds to an example of a scheduling unit.

The setting processing execution unit 101 can switch the power consumption mode between the normal mode and the power saving mode, and maintains the power saving mode until a setting processing instruction is received by the event accumulation management unit 104. After the setting processing instruction is received by the event accumulation management unit 104, the normal mode is entered.
Then, instead of the CPU 200, the setting processing execution unit 101 executes setting processing at the time of initialization processing of the H / W device 301, setting processing at the time of termination processing, and setting processing at the time of mode change processing of the H / W device 301. When the execution of the setting process is completed, the mode is shifted to the power saving mode.

The setting process execution unit 102 targets the H / W device 302, and the setting process execution unit 103 targets the H / W device 303.
The setting process execution unit 102 and the setting process execution unit 103 perform the same operation as that of the setting process execution unit 101 for the target H / W device.

FIG. 7 shows an operation example of the CPU 200 according to the present embodiment.
FIG. 8 shows an operation example of the power control apparatus 100 according to the present embodiment.
An example of the operation according to the present embodiment will be described with reference to FIGS.

First, the CPU 200 determines whether any of initialization processing, termination processing, and mode change processing of the H / W device is necessary (S701).
If any of these processes is necessary (YES in S701), the CPU 200 transmits a setting process instruction to the power control apparatus 100 (S702).
If the current mode is the normal mode, the CPU 200 shifts to the power saving mode (S703).
If the CPU 200 is already in the power saving mode, the CPU 200 maintains the power saving mode.
In the setting process instruction transmitted in S702, the type of setting process executed by the power control apparatus 100 is any of the setting process at the initialization process, the setting process at the end process, and the setting process at the mode change process. And which of the H / W devices 301 to 303 is to be set is described.

In the power control apparatus 100, when the event accumulation management unit 104 receives the setting processing instruction from the CPU 200 (YES in S801), the event accumulation management unit 104 outputs the setting processing instruction from the CPU 200 to the event processing unit 105, The processing unit 105 is shifted from the power saving mode to the normal mode (S802).
In addition, the event processing unit 105 analyzes the input setting processing instruction to identify the H / W device that is the target of the setting processing, and also describes the contents of the setting processing (setting processing at the initialization processing, end processing Which of the setting process and the setting process at the time of the mode change process) is specified (S803).
In parallel, the event processing unit 105 generates a plurality of events necessary for executing the setting process, and schedules the event processing order based on the order restriction of each event.

The event processing unit 105 shifts the setting process execution unit corresponding to the H / W device that is the target of the setting process from the power saving mode to the normal mode (S804).
In the following description, it is assumed that the H / W device that is the target of the setting process is the H / W device 301, and therefore the setting process execution unit that executes the setting process is the setting process execution unit 101. .
Accordingly, in S804, the event processing unit 105 shifts the setting process execution unit 101 from the power saving mode to the normal mode.

Next, in accordance with the scheduling of the event processing unit 105, the setting process execution unit 101 causes the H / W device 301 to perform the setting process specified in S803 (setting process at the initialization process, setting process at the end process, Any one of the setting processes during the mode change process) is executed (S805).
When the setting process is completed (YES in S806), the setting process execution unit 101 and the event processing unit 105 each shift to the power saving mode (S807).
Next, the event accumulation management unit 104 generates a setting process execution completion notification for notifying that the setting process for the H / W device 301 has been completed, and transmits the generated setting process execution completion notification to the CPU 200 (S808).

  When receiving the setting processing execution completion notification from the power control apparatus 100 (YES in S704), the CPU 200 shifts to the normal mode if necessary, and sets the power saving mode if transition to the normal mode is not necessary. Maintain (S705).

As described above, since the power control apparatus 100 executes the setting process for the H / W device instead of the CPU 200, the CPU 200 can be set in the power saving mode.
Since the power control apparatus 100 has lower power consumption than the CPU 200, the power consumption of the entire system can be suppressed compared to the case where the CPU 200 performs setting processing for the H / W apparatus in the normal mode.
In addition, since the power control apparatus 100 shifts to the normal mode only with the minimum necessary elements and time for executing the setting process for the H / W apparatus, the power control apparatus 100 itself can minimize the power consumption. Can do.

For example, as shown in FIG. 5, the power control apparatus 100 is realized by a sub CPU 500 (sub processor apparatus) that complements the CPU 200.
That is, the event accumulation management unit 104, the event processing unit 105, and the setting process execution units 101 to 103 shown in FIG. 2 are used as programs, and the sub CPU 500 executes these programs, thereby realizing the function of each element.
The sub CPU 500 consumes less power than the main CPU 200.
The sub CPU 500 can access, for example, a memory (RAM: Random Access Memory) not shown in FIG. 5, and the sub CPU 500 executes a program loaded in the memory to execute the embodiment. The operations shown in 1 to 3 can be realized.
The sub CPU 500 functions as the block that functions as the event accumulation management unit 104, the block that functions as the event processing unit 105, the block that functions as the setting processing execution unit 101, the block that functions as the setting processing execution unit 102, and the function that functions as the setting processing execution unit 103 If the blocks are divided into blocks, the power consumption can be reduced by shifting the power consumption mode of each block to the normal mode or the power saving mode according to the procedure shown in FIG.
If such control is not possible, the sub CPU 500 starts when receiving a setting processing instruction from the CPU 200 and shifts to the normal mode. When the sub CPU 500 transmits a setting processing execution completion notification to the CPU 200, the sub CPU 500 returns to the power saving mode. Plan

In addition, the power control apparatus 100 can be partially turned ON / OFF (the power consumption mode can be switched between the normal mode and the power saving mode in units of blocks) or one or more ASICs or You may make it implement | achieve in FPGA.
When the power control apparatus 100 is realized by an ASIC or FPGA, it is possible to save power by shifting the power consumption mode to the normal mode or the power saving mode for each block in the procedure shown in FIG. it can.

When the power control apparatus 100 is realized by the sub CPU 500 and a program, the event processing unit 105 is simulated as an operation for scheduling a plurality of tasks (setting process execution units 101 to 103).
The sub CPU 500 implements the event processing unit 105 by reading a program describing the operation to be simulated from a ROM (Read Only Memory) and executing it using the RAM as a work area.
Further, the sub CPU 500 schedules the event waiting of a plurality of independent tasks having no dependency as the operation of the event processing unit 105 to concentrate on the same time, so that the CPU 200 and the sub CPU 500 do substantially nothing. Thus, the waiting time without a long time becomes longer, so that the sleep mode and the power can be turned off, and the power consumption can be further reduced.
In other words, when two or more setting processing instructions for two or more setting execution processing units to execute setting processing are input by the event accumulation management unit 104 at the same time, the event processing unit 105 sets two or more settings. By scheduling the execution order of events so that the execution of the setting process in the execution processing unit is completed at the same time, the power consumption can be reduced.
