Prefetch coverage
Did you know?
Web1. Prefetch coverage: This is the percentage of a program’s memory accesses that were initiated by the prefetcher. Percentage reduction in cache misses is directly related to prefetch coverage. 2. Prefetch accuracy: This is the percentage of prefetch requests that were later accessed by the program. 1. WebDec 19, 2012 · A method, an apparatus, and a non-transitory computer readable medium for tracking accuracy and coverage of a prefetcher in a processor are presented. A table is …
Websimple IP-stride prefetcher can provide high prefetch coverage, in this case. Here is another access pattern for IPB from a benchmark named mcf: C0,C1,C3,C4,C6,C7. The stride … Websoftware data prefetching mechanism [9] falls significantly short of an ideal (in terms of accuracy, coverage, and time-lines) data prefetcher. In our investigation, we find that the existing static software-based solutions fail to prefetch mem-ory blocks in a timely manner, thereby missing significant performance opportunities.
Cache prefetching is a technique used by computer processors to boost execution performance by fetching instructions or data from their original storage in slower memory to a faster local memory before it is actually needed (hence the term 'prefetch'). Most modern computer processors have fast and local … See more Cache prefetching can either fetch data or instructions into cache. • Data prefetching fetches data before it is needed. Because data access patterns show less regularity than instruction patterns, accurate … See more Cache prefetching can be accomplished either by hardware or by software. • Hardware based prefetching is typically accomplished by having a dedicated hardware mechanism in the processor that watches the stream of instructions or data being … See more • While software prefetching requires programmer or compiler intervention, hardware prefetching requires special hardware mechanisms. • Software prefetching works well only with loops where there is regular array access as the programmer has to … See more • Prefetch input queue • Link prefetching • Prefetcher • Cache control instruction See more Stream buffers • Stream buffers were developed based on the concept of "one block lookahead (OBL) scheme" proposed by See more Compiler directed prefetching Compiler directed prefetching is widely used within loops with a large number of iterations. In this technique, the compiler predicts future … See more There are three main metrics to judge cache prefetching Coverage Coverage is the fraction of total misses that are eliminated because of prefetching, i.e. See more Websoftware data prefetching mechanism [9] falls significantly short of an ideal (in terms of accuracy, coverage, and time-lines) data prefetcher. In our investigation, we find that the existing static software-based solutions fail to prefetch mem-ory blocks in a timely manner, thereby missing significant performance opportunities.
