Abstract

The invention discloses an instruction verification method, and an instruction verification device. The method comprises the following steps: obtaining a machine instruction code, wherein the machine instruction code is generated based on instruction configuration information of the machine instruction code in an instruction configuration file; sending the machine instruction code to an instruction decoder in a CPU, so as to enable the CPU to start to execute instruction processing on the machine instruction code from the instruction decoder, and generating an execution result of the machine instruction code; comparing the execution result of the machine instruction code with a standard result corresponding to the machine instruction code so as to judge whether the machine instruction code is correctly executed by the CPU or not according to a comparison result. According to the technical scheme provided by the invention, the instruction verification efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an instruction verification method and an instruction verification device. Background technique [0002] In the process of designing a CPU (Central Processing Unit, central processing unit), the CPU can be used to process each instruction in the instruction set, and by verifying whether the instructions are executed correctly, it can be judged whether the function of the designed CPU is normal. [0003] For example, a reduced instruction set processor (Reduced Instruction Set Computer, RISC) can follow figure 1 The verification flow shown performs instruction verification. exist figure 1 In the process shown, it is first necessary to write a test code in C language or assembly language, and the test code can be compiled into a machine instruction code that can be recognized by a processor through a software compiler. The machine instruction code can be loaded into the ...
