Abstract: A pipelined processor includes a branch acceleration technique which is based on an improved branch cache. The improved branch cache minimizes or eliminates delays caused by branch instructions, especially data-dependent unpredictable branches. In pipelined and multiply pipelined machines, branches can potentially cause the pipeline to stall because the branch alters the instruction flow, leaving the prefetch buffer and first pipeline stages with discarded instructions. This has the effect of reducing system performance by making the branch instruction appear to require multiple cycles to execute. The improved branch cache differs from conventional branch caches. In particular, the improved cache is not used for branch prediction, but rather, the improved branch cache avoids stalls by providing data that will be inserted into the pipeline stages that would otherwise have stalled when a branch is taken.
