Conventional processors use a fully-associative store queue (SQ) to implement store-load forwarding. Associative search latency does not scale well to capacities and bandwidths re...
Memory latency tolerant architectures support thousands of in-flight instructions without scaling cyclecritical processor resources, and thousands of useful instructions can compl...

Abstract. The load-store queue (LQ-SQ) of modern superscalar processors is responsible for keeping the order of memory operations. As the performance gap between processing speed a...
Multicore processors have emerged as a powerful platform on which to efficiently exploit thread-level parallelism (TLP). However, due to Amdahl’s Law, such designs will be incr...
Buffering more in-flight instructions in an out-of-order microprocessor is a straightforward and effective method to help tolerate the long latencies generally associated with ...
