WebNov 27, 2012 · * rip based prefetcher, but it cuts off at jumps in rips of 2000B I believe. Also.. no documentation on how many rips it can track. Any help with that? * L2 pref * does it always bring in the next line to HW pref requests. I imagine if a stride of 512 B were found it wouldn't be benefiical to bring in the next line after that, at 576.

WebReference Prediction Tables (RPT) is a strided prefetching heuristic originally proposed by Chen and Baer in 1995 [14]. Although improvements to the original design have been proposed [15], the basic design is the same. RPT is related to the earlier Stride Directed Prefetcher (SDP) [16]. SDP used a table storing the PC of each load and the ... WebIP Valid?
