Combining data prefetching with non-blocking loads to alleviate cache …
WebMar 1, 1999 · The effectiveness of non-blocking loads on cache conflicts is obvious in combination with the large external (secondary or third level) caches. In the situation where severe cache conflicts occur, many useful data are purged out of the primary cache. The probability that the data purged out of the primary cache still remains in the external ... WebIn [7] a non-blocking cache architecture for FPGA platforms is proposed. Aimed at FPGAs, unlike ASIC non-blocking caches, this architecture does not employ content-addressable memories (CAM). ...
