摘要
An instruction fetch unit for fetching instructions from an instruction cache of a processor. The fetch unit includes a next fetch address mechanism generating predicted next fetch addresses, the next fetch address mechanism generating a next fetch address for a fetch bundle over at least two cycles of the processor. The next fetch address mechanism determines the next fetch address based on whether a control transfer instruction from an intermediate set of fetched instructions is taken.
