The research and design of branch prediction based on multicore heterogeneous

Aiming at those problem that it was difficult to improve the processor performance only by improving the single core frequency, as well as superscalar pipeline stall when process a branch instruction, the architecture of heterogeneous multi-core processor which used B-Cache structure and C-Core processor controller was introduced in this paper. The new architecture avoided the pipeline flushed due to branch miss-predict, and improve overall efficiency of Multi-Core processor.
