Abstract
A processor employs a first instruction cache, a second instruction cache, and a fetch unit coupled to the first instruction cache and the second instruction cache. The fetch unit generates a branch target address responsive to a branch instruction which includes a displacement. Additionally, the fetch unit selects one of the first instruction cache and the second instruction cache from which to fetch instructions stored at the branch target address responsive to a size of the displacement.
