Embodiment Construction

[0021] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The present invention does not run a complete WINDOWS operating system on the LINUX operating system, but only adopts a series of interfaces, mechanisms and resources (which can be referred to as WINAPI) and a set of virtual X86 CPUs that are functionally equivalent to the WINDOWS operating system. environment. WINAPI implements WINDOWS's file, process, graphics, security and other functional interfaces on the LINUX operating system, and connects with it when the X86 executable file is loaded in the form of a shared library. The X86 CPU execution environment simulates a real X86 ...

Abstract

The invention discloses a method for operating Windows application software on a Linux operating system of a million instructions per second (MIPS) version. The Windows application software can be directly operated on the Linux operating system of the MIPS version by using a high-speed X86 instruction simulation method, a central processing unit (CPU) environment management method, a Windows application programming interface (API) environment management method and the like, a Windows operating system is not required, and revising of source codes of Windows software is not required. With tool software which is designed by using the method, a user can use software, which can be only operated on a Windows platform, on a computer of an MIPS framework as randomly as on an X86 computer in spiteof difference between a bottom-layer hardware platform and an operating system, so that a supporting range of application software by the computer of the MIPS framework is expanded, and the method has a high practical value.

Description

technical field [0001] The invention relates to operating system technology and X86 / MIPS instruction set technology, in particular to a method for converting an X86 program into a MIPS program and running it on the MIPS version of the LINUX operating system. Background technique [0002] With the country's continuous emphasis on self-controllability, the Loongson processor with the domestic MIPS architecture has been promoted more and more deeply. It is becoming more and more important to solve the problem of its software support ability, especially supporting mature software on the WINDOWS platform. However, the application software on the WINDOWS platform generally uses the X86 instruction set, using the interfaces, mechanisms and resources provided by WINDOWS, while the MIPS-based Loongson processor generally uses the LINUX operating system. The differences in operating systems and hardware make The application software on WINDOWS cannot run directly on the LINUX platfor...
