Energy consumption management method for inserting system

Abstract

The invention provides an energy consumption management method for an embedded system, implemented by dynamic power supply management support module, comprising: policy management module, idle detection module, and performance detection module, where the policy management module makes effective power supply management at system layer so as to implement system performance and power saving, and gives attention to idle state and executed load of system, and self-adaptively regulates equipment idle time according to system task executing state and makes the system enter a corresponding low-power state when the idle time continues to a certain extent; the idle detection module provides idle information of CPU and operating system and monitors the idle thread or activity of a given working load in the operating system and provides policy-making parameter information for the policy management module; and the performance detection module monitors CPU utilization ratio and utilization conditions of main memory and provides accurate executed load information for the policy management module.

Description

technical field [0001] The invention belongs to the technical field of energy consumption management of embedded systems. In particular, it relates to an energy management method for an embedded system. Background technique [0002] With the rapid development and wide application of embedded technology, embedded technology has been closely integrated with people's daily life. Both civilian and military products have put forward higher and higher requirements for the application of embedded systems, but the performance of The improvement also brings the problem of increased system energy consumption. [0003] There are mainly static low power consumption technology and dynamic low power consumption technology in the existing embedded system low power consumption realization technology. Static low power consumption technology mainly designs electronic components from the perspective of hardware; dynamic low power consumption technology is realized f...

AI Technical Summary

Problems solved by technology

[0004] However, neither the static low power consumption technology nor the dynamic low power consumption technology starts from the limitation of terminal resources and the characteristics of the application program itself, and often has disadvantages such as complex technology and ineffective low power consumption effects.
