Problems solved by technology

Although such a system can make full use of the computing power of the multi-core processor, it does not make full use of the fault tolerance of the multi-core processor itself, and because the multiple operating systems running on the hypervisor are virtual machines, the security of these operating systems and stability are affected by each other

Abstract

The invention discloses a control method for multiple operating systems of a multi-core computer, comprising the following steps: when the computer is started, different memory spaces and processor cores are allocated for the operating systems, the processor cores are controlled to skip to the respectively-allocated kernel image entrances of the operating systems in sequence, kernel images of the operating systems are respectively loaded to the preset address of the memory of the computer, so that the operating systems can be started; in the running process of the computer, the operating systems respectively use the respectively-allocated processor cores and memory spaces to execute various operations. According to the control method, different memory spaces and processor cores are allocated for multiple operating systems, the multiple operating system installed in the multi-core processor are controlled to manage the multiple processor cores, each operating system uses the allocated privately-owned memory, so that the error tolerance of the multi-core processor is sufficiently utilized while the computing capability of the multi-core processor is utilized.

Description

technical field [0001] The invention relates to the field of computer operating systems, in particular to a method for controlling multiple operating systems on a multi-core computer and the multi-core computer. Background technique [0002] Since Stanford University in the United States first proposed the idea of ​​on-chip multi-processor and the first multi-core structure prototype in 1996, IBM launched the first commercial multi-core processor POWER4 in 2001, and then to the large-scale application of Intel and AMD multi-core processors in 2005, and finally Up to now, multi-core has become the mainstream of the market, and multi-core processors have experienced more than ten years of development. In this process, the application range of multi-core processors has covered many fields such as multimedia computing, embedded devices, personal computers, commercial servers and high-performance computers, and multi-core technology and related research have also developed rapidl...
