But load instructions would be issued with memory dependencies are known. Memory dependencies cannot be resolved prior to execution; therefore load instructions would be issued with prior store effective address calculated. This paper introduces the load forwarding history table (LFHT) for speculative executed load instructions by using load-forwarding behavior. This mechanism can be used to permit load instructions to be speculative executed without wait for prior store effective address calculated. The LFHT might provide about 9% average speedup up over baseline architecture in our scheme. Advisor Committee Jong-Jiann Shieh - advisor
