System virtual machine for microprocessor without interlocked piped stages (MIPS) platform

Abstract

The invention aims at the problem that a microprocessor without interlocked piped stages (MIPS) platform is not assisted and supported by hardware, discloses a system virtual machine for the MIPS platform by using a lightweight virtualization technology, and provides high-efficiency virtualization infrastructure support for upper-layer application. Modules of the virtual machine mainly comprise physical hardware, a host operating system (OS), a virtual machine inner core, virtual hardware, an equipment model, a client OS and a host quick emulator (QEMU) process. Execution modes of the virtual machine mainly comprise a management mode, an inner core mode and a user mode. According to an application request, by adoption of the virtual machine, the technical problem that an MIPS processor is not assisted and supported by the hardware is solved; and by adoption of a lightweight inner core virtual machine technology, virtualization application requirements in the embedded field can be met, and the virtualization application requirements in the field of servers can be also met. Therefore, the virtual machine has the characteristics of light weight, wide application prospect, remarkable economic benefit and the like.

Description

(1) Technical field [0001] The invention discloses a system virtual machine, in particular to a system virtual machine (abbreviated as MIPSVM) for a MIPS platform, where MIPS refers to "Microprocessor without interlocked piped stages". It belongs to the field of computer technology. (2) Background technology [0002] System virtualization is an important research direction in the combination of computer system architecture and computer system software. It abstracts the physical resources of the computer system by adding a virtual machine monitor (Virtual Machine Monitor, VMM) between the computer system hardware and the operating system, and isolates the close dependencies between the hardware system structure and software; through dynamic organization CPU, memory, I / O and other physical resources, flexibly build multiple isolated virtual computers to meet diverse application needs; improve resource utilization by exploring the parallelism of time and space between applicat...

AI Technical Summary

Problems solved by technology

However, summarizing the existing research results and implementation systems, the existing research and inventions have the following trends and problems: In terms of architecture, most of them are designed, implemented, and improved key technical inventions for X86 and other architecture platforms. In the invention of the embedded system platform, virtual machine application technology (such as the use of virtual machine technology to assist the realization of virtualized multi-window display and detection [3] [5], etc.)

For the MIPS platform, there are relatively few researches on the system virtualization technology for the MIPS platform, especially for its non-hardware-assisted problem, the overall architecture design of the system virtual machine based on the lightweight virtual machine (kernel virtual machine KVM) Lack of research and invention of its key technologies (CPU virtualization, memory virtualization and IO virtualization, etc.)
