Read-After-Read Memory Dependence Prediction

: We identify that typical programs exhibit highly regular read-after-read (RAR) memory dependence streams. We exploit this regularity by introducing read-after-read (RAR) memory dependence prediction. We also present two RAR memory dependence prediction-based memory latency reduction techniques. In the first technique, a load can obtain a value by simply naming a preceding load with which a RAR dependence is predicted. The second technique speculatively converts a series of LOAD1-USE1,...,LOADN-USEN chains into a
