Energy-saving system, processing device and method of cpu and soc bridge chip architecture

Abstract

The invention provides an energy-saving type system of a CPU and SoC chip framework as well as a processing device and method. The energy-saving type system comprises a first processing unit CPU, a system on chip SoC chip and a processing device, wherein the SoC chip is configured with a second CPU; the first CPU is connected with the second CPU to ensure that the first CPU and the second CPU have a same physical address space; the processing device is connected with each of the first CPU and the second CPU, and is used for obtaining the load state of an operation system OS of the energy-saving type system and controlling the operation states of the first CPU and the second CPU according to the load state of the OS of the energy-saving type system. The energy-saving type system provided by the invention can be used for solving the problem that the 3A+2H type computer in the prior art is relatively bad in resource using efficiency as only the processing unit 3A is in operation state and the CPU in 2H of the SoC chip is in the dormant state when the 3A+2H type computer is operated.

Description

technical field [0001] The invention relates to computer technology, in particular to an energy-saving system, a processing device and a method based on a CPU and a SoC bridge chip. Background technique [0002] At present, in order to improve the performance of the computer, a computer architecture of a processor (Central Processing Unit, referred to as: CPU) and a system on chip (System on Chip, referred to as: SoC) chip can usually be used; in this computer architecture, the SoC The chip is only used as a bridge chip of the CPU, that is, it directly interacts with the CPU for data and instructions, and acts as a processing chip connecting the bridge. The computer of above-mentioned CPU and SoC bridge chip structure can be the computer of 3A+2H type for example, and wherein, 3A is main CPU, and 2H itself is a SoC chip; This SoC chip comprises independent core, in this system as the bridge chip of 3A use. Specifically, when the 3A+2H type computer is running, after the ke...
