Memory Access Predictors (STeMS project page is here)
While memory capacity in recent years has increased commensurately with
processor speeds, memory speeds have primarily lagged behind. My research
focuses on mechanisms for a novel memory system that "proactively" moves
and places data among the cache hierarchy levels in anticipation of a
processor memory access, to hide the long memory latency. The key
mechanisms enabling proactive memory are memory access predictors that
monitor program execution, capture processor memory access patterns, and
accurately predict subsequent memory accesses.
