Integrity detection method, device and electronic device for processor instruction set

Abstract

Embodiments of the present invention provide a completeness detection method, device, and electronic device for a processor instruction set, wherein the method includes: obtaining all instruction codes in the processor instruction set, and calculating the expected codes of the processor instruction set based on this. The total number of instructions and the total number of theoretical and actual instructions; if the total number of theoretical and actual instructions is not equal to the total number of expected instructions, then perform overlapping clustering processing on all instruction codes, and calculate each class The number of overlapping instructions in the calculation, calculate the total number of instructions that are repeatedly calculated; based on the total number of theoretical actual instructions and the total number of instructions that are repeatedly calculated, calculate the total number of real actual instructions, and judge the Whether the actual total number of instructions is equal to the total number of expected instructions, if so, determine that the instruction set of the processor is complete, otherwise, determine that it is incomplete. The embodiments of the present invention can effectively eliminate calculation errors, thereby effectively improving the accuracy of detection results.

Description

Technical field[0001]The present invention relates to the field of processor, and more particularly to a complete detection method, apparatus and electronic device of a processor instruction set.Background technique[0002]During the testing process of the processor instruction set, the completeness of the processor instruction set is critical, because if the test set is not guaranteed, the coverage rate of the instruction set test cannot be guaranteed. And those test blind spots are likely to have design defects. The completeness of the processor instruction set describes whether the command set contains all instruction possibilities. Take the 32-bit fixed-length instruction set as an example, if the instruction set contains all 232The instructions are complete, and if the instruction set contains less than 232The instruction set is not complete.[0003]The processor instruction set generally describes the instruction coding, each instruction encoding can represent a plurality of instr...

Problems solved by technology

However, if an instruction is represented by multiple instruction codes, then the instruction will be recalculated. For example, there are many instructions represented by multiple instruction codes in the ARM processor instruction set, which will result in the calculated instruction There is an error in the total number of bars, which affects the accuracy of the final test result
