Abstract

The embodiment of the invention provides a multi-cycle instruction processing method, a processor and electronic equipment, belongs to the field of computers, and is used for solving the technical problem that a single-cycle instruction processor does not support a user-defined multi-cycle instruction. The processor is provided with a user-defined instruction execution unit which is used for generating active pause signals and controlling other functional units to pause operation in the execution stage of a user-defined multi-cycle instruction through the active pause signal, wherein the otherfunctional units are functional units except the user-defined instruction execution unit in an pipeline architecture, and the user-defined multi-cycle instruction is a user-defined instruction including multiple microoperations in the execution stage; and the user-defined instruction execution unit is further used for sequentially executing the plurality of microoperations included in the execution stage of the user-defined multi-cycle instruction during the pause of the other functional units. According to the method, the processor and the electronic equipment provided by the invention, thecustom multi-cycle instruction can be processed based on the single-cycle instruction processor.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a multi-cycle instruction processing method, processor and electronic equipment. Background technique [0002] The reason why a computer can process instructions and perform calculations is that the central processing unit (CPU) can fetch an instruction from the memory storing the program, execute the instruction after decoding, and then fetch the instruction, decode, and execute the instruction. Execute the command until a stop command is encountered. [0003] At present, most processors (eg, CPU, central processing unit) process instructions in a pipelined manner. The pipeline method of the processor is similar to the assembly line in industrial production. In the processor, a plurality of circuit units with different functions form an instruction processing pipeline, and an instruction is divided into multiple microcomputers corresponding to the number of circuit ...
