Abstract

The invention discloses a virtual hardware system comprising a father hardware and a virtual hardware, wherein, the father hardware reads instruction data from the virtual hardware, operates a processing flow corresponding to the instruction data and sends the processing result to the virtual hardware, and the virtual hardware stores instruction data with mapping relation to the preappointed instruction and receives the processing result from the father hardware. The invention also discloses an instruction execution method based on the virtual hardware. The invention is capable of reading and converting the instruction data of a virtual hardware via the father hardware, calling internal resources, such as performance function and various advanced resources according to the instruction, and utilizing the called internal resources to operate the processing flow corresponding to the instruction, thereby reducing instruction execution cycle and increasing instruction execution speed of the virtual hardware. Moreover, the invention does not need to store the same logic code for realizing the same function in the father hardware and the virtual hardware respectively, thus saving system resources.

Description

technical field

[0001] The invention relates to computer technology, in particular to a virtual hardware system and an instruction execution method based on the virtual hardware system. Background technique

[0002] A computer system includes a processor for executing a specific set of system instructions. Different types of processors can only execute instruction sets corresponding to the type of processors, that is, instruction sets of different processors are incompatible. However, by executing different instruction sets, various types of processors can show different performance advantages. For example, the instruction set of Intel80X86 central processing unit (CPU) is based on the complex instruction set computer (CICS) format, which can realize complex processing functions; The Motorola Power PC's instruction set is based on the Reduced Instruction Set Computer (RISC) format, which can perform simple processing functions at high speed.

[0003] The prior art solves t...
