Problems solved by technology

Traditional virtual machines (such as: Bochs IA-32Emulator: http: / / bochs.sourceforge.net / ) When constructing a user execution environment with multi-processing resources, in order to realize the synchronization of execution units, the execution content of multiple processing units is actually placed in a loop for serial execution, and its efficiency is very low

Abstract

The invention discloses a parallel multi-processor virtual machine system supporting simultaneous CPU execution, which includes a virtual machine and an operating system running on the virtual machine. The virtual machine system can simulate at least one virtual processor, which includes a processor parallel simulation module, a memory management module, an interrupt control simulation module and a peripheral simulation module; the machine instructions of the operating system are transmitted through the memory management module of the virtual machine For the processor simulation module, the processor simulation module can simulate multiple virtual processors to execute the operating system instructions translated by the instruction translation module, and make them execute in parallel. At the same time, the present invention proposes synchronization and access control in the process of parallel execution Algorithm; the interrupt control analog module is responsible for coordinating the peripheral analog module and the processor analog module. The invention is particularly suitable for virtualizing a parallel execution environment of a complete simulated hardware on an SMP server or a multi-core server.

Description

technical field [0001] The invention relates to a computer system structure, in particular to a parallel multi-processor virtual machine system, which enables multiple virtual processors to run in parallel on a modern multi-processor server platform. Background technique [0002] The operating system plays a very special role in today's personal computers and servers. It is like a bridge that bridges the gap between user applications and hardware platforms. For a long time in the past, only one operating system could run on a computer at any given time. Therefore, in order to enable multiple operating systems, or application programs of different operating systems to run simultaneously on the same computer, scientists have invented many methods and technologies. [0003] Virtual machines are widely used as a powerful and convenient technology. [0004] System-level virtual machines simulate all components of a computer system with high precision. In this way, the operatin...
