Embodiment Construction
[0025] refer to figure 1 , the present invention is a processor energy-saving method for reducing power consumption, comprising the following steps:
[0026] A. Divide the processor time into several equal time periods;
[0027] B. At the beginning of each time period, check whether the preset energy-saving conditions are met, and if so, control the processor to enter the energy-saving mode; otherwise, wake up the processor to work at full speed.
[0028] As a further preferred implementation manner, the wake-up processor performs full-speed work, and re-enters the energy-saving mode after completion.
[0029] As a further preferred embodiment, the step B is specifically to detect whether a task arrives at the beginning of each time period, and if so, control the processor to enter an energy-saving mode; otherwise, wake up the processor to work at full speed.
[0030] As a further preferred embodiment, the length of the time period can be set independently according to the s...

The invention discloses a processor energy saving method and system for reduction of power consumption. The processor energy saving method for reduction of the power consumption comprises the steps that the time of a processor is divided into a plurality of same time periods; whether preset energy saving conditions are met or not is detected in the beginning stage of each time period, if yes, the processor is controlled to be in an energy saving mode, and if not, the processor is awakened and conducts full-speed working. The processor energy saving system comprises a division unit and a detection unit. According to the processor energy saving method and system, the processor and an internal memory can automatically work in a lowest power consumption state, and therefore the operation requirement of the working load at present is met under the condition that performance is not affected; due to time period division processing, various processes can be conveniently handled with, various task states can be effectively controlled to be in the energy saving mode, time division multi-tasking is achieved, limited resources of the processor can be fully utilized, the processor energy saving method and system can be applied to various occasions with the rigorous requirement for the battery capacity, and the energy consumption is greatly reduced. The processor energy saving method and system can be widely applied to wireless ad hoc networks.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a processor energy-saving method and system for reducing power consumption. Background technique [0002] Nodes in wireless ad hoc networks usually use batteries to provide energy, while wireless sensor network nodes are the most basic components of wireless sensor networks, responsible for information collection, processing and transmission. Wireless sensor nodes are small in size and usually use energy-limited devices. Battery. Since sensor nodes have very limited computing, storage, and communication capabilities, they need to communicate frequently with distant base stations. Network lifetime measured by the time all nodes in the network are depleted of energy or no longer provide effective event detection, directly affecting the effectiveness of the network. [0003] Existing wireless sensor network nodes are mainly composed of control unit, sensing unit, po...
