Abstract

The invention provides a conditional jump instruction processing method. The method comprises the following steps: determining an instruction fetching address, and fetching a target instruction from an instruction cache according to the instruction fetching address; analyzing the target instruction to obtain an instruction type; if the instruction type is a conditional jump instruction, controlling the conditional jump instruction to jump according to a preset jump rule; when the conditional jump instruction jumps normally according to the preset jump rule, sending corresponding instruction information to a first cache; and when the conditional jump instruction jumps abnormally not according to the preset jump rule, sending the corresponding instruction information to a second cache. According to the invention, the problem that a dynamic prediction method is easily influenced by an algorithm, resources, a compiler and application adaptation can be solved, and the instruction execution efficiency of a processor is improved. The invention further provides a conditional jump instruction processing system, a computer readable storage medium and electronic equipment, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of communication of electronic equipment, in particular to a processing method, system and related devices for conditional jump instructions. Background technique [0002] RISC-V (Reduced Instruction Set Computing-Five, the fifth generation of reduced instruction set), is a new instruction set established on the basis of continuous development and maturity of instructions. It has the advantage of latecomer, clear and simple structure, and modular design It can be freely matched according to the needs, flexible and convenient, strong in portability, and has a complete tool chain. However, most instruction designs still follow the traditional instruction pipeline, and the BHT and BTB modes of dynamic prediction are adopted for the processing of branch instructions. When the instruction prediction fails, the pipeline needs to be refreshed and the instruction fetched again, which seriously affects the processor...
