Embodiment Construction
[0038] In the branch prediction scenario based on BTB (Branch Target Buffer, branch target buffer), the embodiment of the present invention can store branch information in the cache, so as to judge whether the branch prediction result is correct by using the branch information stored in the cache during the instruction fetching phase; When judging the branch prediction error, it is possible to correct the branch prediction error in the fetching stage, thereby reducing the filling of the pipeline with instructions caused by the branch prediction error and the corresponding execution results, and reducing the resource consumption and delay of the pipeline.
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
