Information processing device and power consumption management program

An information processing device and power technology, which is applied in the directions of data processing power supply, program control design, electrical digital data processing, etc., can solve the problem that the operation period of application program 1 and application program 2 cannot be adjusted, and the power consumption of OS3 and device 4 cannot be shortened. The effect of reducing power consumption is achieved due to problems such as the increased period.

Problems solved by technology

[0013] However, the polling intervals T1 and T2 of conventional portable devices are determined by the application creators of the application 1 and the application 2 without considering the power consumption of the OS 3 and the device 4.
Therefore, conventional portable devices cannot adjust the period during which the application program 1 and the application program 2 operate, and cannot shorten the period during which the power consumption of the OS 3 and the device 4 increases.

Abstract

The problem is to provide an information processing device capable of suppressing power consumption and a power consumption management program. It is characterized in that an information processing device that performs a plurality of processes in parallel includes: a plurality of processing units; and an adjustment unit that determines processing for each processing unit. The processing interval of each unit is adjusted in stages in such a way that the processing timings of the plurality of processing units match.

Description

technical field [0001] The present invention relates to an information processing device that performs a plurality of processes in parallel, and a power consumption management program used in the information processing device. Background technique [0002] When portable devices such as mobile phones, PDAs (Personal Digital Assistants), and notebook PCs are driven by batteries, the battery operating time will vary depending on the power consumption. [0003] In recent years, among portable devices, devices on which a multitasking OS is installed are increasing. Among portable devices installed with a multitasking OS, there are devices that can add rich client software (rich software) such as functions, user interface expressiveness, operability, and displayed content. [0004] However, a portable device on which a multitasking OS is installed may consume power in vain due to continuous operation of rich software. For example, a smartphone, which is an example of a portable ...
