Reducing memory latency via read-after-read memory dependence prediction
2002
IEEE transactions on computers
AbstractÐWe observe that typical programs exhibit highly regular read-after-read (RAR) memory dependence streams. To exploit this regularity, we introduce read-after-read (RAR) memory dependence prediction. This technique predicts whether: 1) A load will access a memory location that a preceding load accesses and 2) exactly which this preceding load is. This prediction is done without actual knowledge of the corresponding memory addresses. We also present two techniques that utilize RAR memory
