Abstract: Various embodiments of the invention concern methods and apparatuses for power and time efficient load handling. A compiler may identify producer loads, consumer reuse loads, consumer forwarded loads, and producer/consumer hybrid loads. Based on this identification, performance of the load may be efficiently directed to a load value buffer, store buffer, data cache, or elsewhere. Consequently, accesses to cache are reduced, through direct loading from load value buffers and store buffers, thereby efficiently processing the loads.
