Energy-saving type system of CPU and SoC chip framework as well as processing device and method

Abstract

The invention provides an energy-saving system, processing device and method of CPU and SoC bridge chip framework. The energy-saving system provided by the present invention includes: a first processor CPU, a system-on-chip SoC bridge and a processing device configured with a second CPU, wherein the first CPU is connected to the second CPU, so that the first CPU and the second CPU have the same physical address space; the processing device is respectively connected to the first CPU and the second CPU, and is used to obtain the load status of the operating system OS of the energy-saving system, and control the first CPU and the OS according to the load status of the OS of the energy-saving system. The running status of the second CPU. The energy-saving system provided by the present invention solves the problem that when the 3A+2H type computer in the prior art is running, because only the processor 3A is in the running state, the CPU in the SoC bridge 2H is in the dormant state, causing the 3A+2H The problem of poor resource usage efficiency of small computers.

Description

Technical field [0001] The invention relates to computer technology, in particular to an energy-saving system, processing device and method of a CPU and SoC bridge chip architecture. Background technique [0002] At present, in order to improve the performance of the computer, it is usually possible to use a processor (Central Processing Unit, referred to as: CPU) and a system on chip (System on Chip, referred to as: SoC) chip as a computing architecture; in this computing architecture, the SoC chip only serves The CPU's bridge chip uses, that is, directly interacts with the CPU for data and instructions, and acts as a processing chip that connects the bridge. The aforementioned CPU and SoC bridge chip computer may be, for example, a 3A+2H type computer, where 3A is the main CPU and 2H itself is a SoC chip; the SoC chip includes an independent core, which serves as a 3A bridge in the system use. Specifically, during the operation of the 3A+2H type computer, after the core in th...
