Embodiment Construction

[0029] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] One of the core ideas of the embodiments of the present invention is: when the CPU is in an idle state, turn off the power supply of the control unit and the calculation unit, and reduce the power supply voltage of the memory to be lower than the working voltage, thereby achieving the purpose of reducing CPU power consumption.

[0031] refer to figure 1 , which shows the component structure of a CPU device embodiment of the present invention, which may specifically include:

[0032] memory 101 for storing data and instructions;

[0033] The control component 102 is used to control and coordinate the operation of various functional components;

[0034] Operation unit 103, used to complete various arithmetic and logical ope...

Abstract

The invention discloses a CPU, comprising the following components: a memory for storing data and instructions; a control component for controlling and coordinating the operation of each functional component; and an arithmetic component for finishing various arithmetic and logical operations. The CPU further comprises: a sleep order register for generating sleep trigger signals according to configuration when the CPU is in idle condition; a power supply management module for closing the power supplies of the control component and the arithmetic component according to the sleep trigger signals, and reducing the power supply voltage of the memory till lower than the working voltage. The invention can reduce power consumption in idle condition of CPU device, thereby achieving the purpose of saving power consumption.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a method for reducing power consumption of a CPU and a CPU with low power consumption. Background technique [0002] The CPU is widely used. For example, the CPU is used as an important device in various SOCs (System On Chip, System On Chip). In chip design and application, power consumption is an issue that must be considered, and CPU, as an important device, how to reduce its power consumption is also a direction that the existing technology has been eager to improve. [0003] The energy consumed in the circuit can be divided into static power consumption and dynamic power consumption. Among them, the static power consumption is derived from the leakage current when the transistor is not activated, which is exponentially related to the temperature and the switching threshold. Dynamic power consumption refers to the power consumption of capacitor charging and discharg...
