A multiprocessor prefetch scheme is described in which a miss is followed by a prefetch of a group of lines, a neighborhood, surrounding the demand-fetched line. The neighborhood ...
Multicore processors have become ubiquitous in today’s systems, but exploiting the parallelism they offer remains difficult, especially for legacy application and applications ...
—Super-scalar, out-of-order processors that can have tens of read and write requests in the execution window place significant demands on Memory Level Parallelism (MLP). Multi- ...

Instruction supply is a crucial component of processor performance. Instruction prefetching has been proposed as a mechanism to help reduce instruction cache misses, which in turn...
This paper proposes and evaluates hardware mechanisms for supporting prescient instruction prefetch--an approach to improving single-threaded application performance by using help...
