WebThe prefetcher recognizes a sequence of data cache misses at a fixed stride pattern that lies in 32 cache lines, plus or minus. Any intervening stores or loads that hit in the data cache do not interfere with the recognition of the cache miss pattern. Up to twelve independent streams can be handled by the prefetcher.

WebA. Instruction Based Stream Detection One of the challenges of a hardware strided prefetcher is to extract the stride – essentially by reverse engineering. This task is further complicated by the presence of unrelated addresses and the absence of any certainty that there is a strided stream to begin with. Common designs involve memorizing many WebOur attack targets Instruction pointer (IP)-based stride prefetching in Intel processors. Stride prefetcher detects memory access patterns with a regular stride, which are likely to be found in lookup table-based cryptographic implementations.

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].
