Instruction Execution Method and Processor

Abstract

The present invention provides an instruction execution method and a processor. The instruction execution method comprises the following steps of: obtaining an instruction of program code, wherein thepreset position of the program code is provided with an access memory return pipeline instruction, which is used for acquiring the target data and sending the target data back to the instruction pipeline to execute the target data; instruction decoding of program code; if the instruction of the program code is an access-memory-return pipeline instruction, the access-memory-return pipeline instruction being executed, and the decoding of the instruction to be processed in the instruction pipeline being suspended, wherein the instruction to be processed is an instruction located in the instruction pipeline after the access-return pipeline instruction. The instruction execution method provided by the invention, by setting the access memory return pipeline instruction at a preset position in the software code, the processor executes the access memory return pipeline instruction, thereby improving the expansibility and applicability of the software code.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to an instruction execution method and a processor. Background technique [0002] A software program refers to a computer program developed to run on an operating system in order to complete one or several specific functions. A software program, once compiled, performs a specific function when run on a microprocessor. The software program can also have different functions according to the change of the input data, and the selection of different functions is realized through branch instructions. That is to say, all the functions are preset in the software program, but enter different function branches according to different inputs. [0003] Many times, we need to change the execution function of a software program. For example, when a software program executes an error and needs to be diagnosed, a diagnostic function needs to be inserted. Another example is when patchin...

AI Technical Summary

Problems solved by technology

[0004] However, pipeline flushing is required when exceptions / interrupts occur and context protection is required, making software program changes inefficient and complex

Moreover, some software programs themselves shield exceptions / interruptions, resulting in software programs that cannot be changed, which greatly limits the scalability and applicability of software programs
