  • Data structure-aware prefetching method and device on graphics processing unit
    Patent number: 11520589
    Abstract: The invention discloses a data structure-aware prefetching method and device on a graphics processing unit. The method comprises the steps of acquiring information for a memory access request in which a monitoring processor checks a graph data structure and read data, using a data structure access mode defined by a breadth first search and graph data structure information to generate four corresponding vector prefetching requests and store into a prefetching request queue. The device comprises a data prefetching unit distributed into each processing unit, each data prefetching unit is respectively connected with an memory access monitor, a response FIFO and a primary cache of a load/store unit, and comprises an address space classifier, a runtime information table, prefetching request generation units and the prefetching request queue.
