August undefined, 2024

WebHardware scout is a technique that uses otherwise idle processor execution resources to perform prefetching during cache misses. When a thread is stalled by a cache miss, the processor pipeline checkpoints the register file, switches to runahead mode, and continues to issue instructions from the thread that is waiting for memory. The thread of execution … WebRunahead Execution Prefetching . 2 . Readings Required Mutlu et al., “Runahead execution”, HPCA 2003. Srinath et al., “Feedback directed prefetching”, HPCA 2007.
