Abstract
Various techniques for predicting instruction fetch widths. In one embodiment, a fetch prediction unit in a processor is configured to generate a fetch width that specifies a number of bits to be retrieved in a subsequent fetch from an instruction cache. The fetch prediction unit may also generate a fetch prediction that includes the fetch width in response to a current fetch request. A number of bits corresponding to the fetch width may be fetched from the instruction cache. The fetch width may correspond to a location of a predicted-taken control transfer instruction. This fetch width prediction may lead to power savings in instruction cache accesses.
