摘要:
A system and method to optimize runahead operation for a processor without use of a separate explicit runahead cache structure. Rather than simply dropping store instructions in a processor runahead mode, store instructions write their results in an existing processor store queue, although store instructions are not allowed to update processor caches and system memory. Use of the store queue during runahead mode to hold store instruction results allows more recent runahead load instructions to search retired store queue entries in the store queue for matching addresses to utilize data from the retired, but still searchable, store instructions. Retired store instructions could be either runahead store instructions retired, or retired store instructions that executed before entering runahead mode.
摘要:
Embodiments that dynamically reorganize data of cache lines in non-uniform cache access (NUCA) caches are contemplated. Various embodiments comprise a computing device, having one or more processors coupled with one or more NUCA cache elements. The NUCA cache elements may comprise one or more banks of cache memory, wherein ways of the cache are horizontally distributed across multiple banks. To improve access latency of the data by the processors, the computing devices may dynamically propagate cache lines into banks closer to the processors using the cache lines. To accomplish such dynamic reorganization, embodiments may maintain “direction” bits for cache lines. The direction bits may indicate to which processor the data should be moved. Further, embodiments may use the direction bits to make cache line movement decisions.
