Embodiment Construction

[0019] Embodiments of the present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0020] It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence.

[0021] In related technologies, the schematic diagram of branch jump can be found in the attached figure 1 ,Such as figure 1 As shown, before executing the specific branch A or branch B, there will be a branch judgment step. From the perspective of the CPU, when executing the specific branch A or branch B, there must be a branch judgment process. For the flow chart of branch judgment, please refer to the attached figure 2 ,Such as figure 2 As shown, the branch judgment process includes:

[0022] Step S1, load instructions from memory (unavoidable);

[0023] Step S2, loadin...

Abstract

The embodiment of the invention provides a branch path skipping method and device, a storage medium and an electronic device. The method comprises the steps: acquiring a branch skipping code, wherein the branch skipping code is used for indicating at least two branch paths; determining an assembly code corresponding to the branch jump code, and embedding the branch jump code in the assembly code to obtain a target code, wherein the assembly code is used for achieving jump between the branch paths; under the condition that it is determined that a target branch path included in at least two branch paths needs to be jumped to, generating a target jump instruction used for indicating to jump to the target branch path; replacing a jump instruction included in the target code with a target jump instruction, and jumping to the target branch path based on the target jump instruction. According to the invention, the problem of low branch jump efficiency in the prior art is solved, and the branch jump efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, relate to a branch path jumping method, device, storage medium, and electronic device. Background technique [0002] In related technologies, CPU (Central Processing Unit) often has a long pipeline (an instruction execution mechanism inside a CPU, and there is a certain relationship between the various stages of the pipeline. The collapse of the upper pipeline will lead to the reconstruction of the lower pipeline), making it Achieving instruction parallelism in a small area improves the instruction throughput of the CPU, and the longer the pipeline, the faster the average speed of completing an instruction. On the other hand, there are often conditional branches in the program, which have two follow-up paths: do not take the jump (execute subsequent instructions sequentially) or take the jump (jump to other instruction addresses); It is determined by passing the...
