ABSTRACT:
An instruction pipeline in a microprocessor is provided. The instruction pipeline includes a plurality of pipeline units, each of the pipeline units processing a plurality of instructions including branch instructions. The instruction pipeline further includes a plurality of storage device which store a respective branch information data. Each of the storage devices are associated with at least one of pipeline units. Each respective branch information data is determined as a function of at least one of the branch instructions processed. Two of the pipeline units include branch prediction circuitry for predicting branch direction as a function of the stored branch information data.
