A power consumption management method, a power consumption management device, and a processor

Abstract

A power consumption management method, a power consumption management device, and a processor. The implementation of the method comprises: acquiring operation information from a processor core; if it is determined according to the operation information that the processor core needs to be backed up, first sending a backup control signal to a trigger of the processor core, so that the trigger of the processor core backs up the state of the processor core to a non-volatile memory corresponding to the trigger; and cutting off power supply to the processor core. The problem that the processor runs slowly due to the fact that the processor core needs to visit a centralized memory through a bus is avoided, and the running speed of the processor is accelerated.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a power consumption management method, a power consumption management device, and a processor. Background technique [0002] With the development of semiconductor technology, more and more transistors can be integrated per unit area; but limited by factors such as memory wall, power consumption wall and I / O (input / output, input / output) wall, single-core performance It becomes more and more difficult to improve. Therefore, many-core processors and heterogeneous acceleration have become hot research topics in the industry. Higher processing performance is achieved through many-core processors and heterogeneous acceleration to take full advantage of the huge number of transistors. [0003] Multiple processor cores of many-core processors usually share the main memory and I / O devices. Due to resource competition and local congestion of the on-chip network, each proce...

AI Technical Summary

Problems solved by technology

Since the writing and restoration of the state data of the processor core is realized through serial access through the bus, however, the speed of serial access is slow, which will cause the processor to run slower

In addition, save and restore processes consume high power due to the need to access the centralized memory through the bus
