ABSTRACT:
Described is a Load Unit for processing the data fetch in load instructions. The Load Unit predicts the address for the data fetch such that the fetch can occur earlier than in the typical load processing. By processing the fetch early, the normal cache access cycle can be eliminated reducing overall execution time. Cache misses can be processed in parallel with other execution thereby reducing the performance degradation of cache misses.
