Abstract
An apparatus and method for quickly and efficiently handling mispredicted branch instructions in a computer processor having multiple instruction execution pipelines and utilizing branch delay slot instructions. When a mispredicted branch occurs, all instructions that follow the branch in execution order, including the branch delay slot instruction, die in the pipeline. The delay slot, if it is to be executed, is then reissued to the pipeline.
