Abstract
A differential matching prefetcher for coping with irregular memory access includes: an access index table, an access target table, a differential matching module, an index queue, an indirect memory access candidate scoreboard, an address generator, an indirect memory access relationship table, a prefetch status handling register, a repetition filter, a continuous address filter, and a range prefetch table. The differential matching prefetcher is configured to monitor events of access requests and data responses between a computing core and a first level of cache, as well as between the first level of cache and a second level of cache. The differential matching prefetcher may be applied in various general-purpose computing architectures adopting a hierarchical storage design to realize mode capture and data prefetch for irregular indirect memory access, reduce long-delay storage access overhead caused by the irregular memory access, and increase instructions per cycle (IPC) of the computing architectures.
