Microprocessor speeds have been improving much faster than memory speeds, resulting in the CPU spending a larger and larger amount of time waiting for data. Processor designers have employed several ways to improve memory performance, including hierarchical caching, prefetching, and faster memory chips. Yet, memory accesses still represent a major performance bottleneck and much remains to be done to tolerate the increasing memory latencies. Load-value prediction has been shown to effectively hide some of this latency. However, the hardware required to achieve good performance is substantial, making load-value prediction unappealing in light of increasing power constraints. In this paper, we present a novel predictor that significantly increases CPU performance while at the same time decreasing the energy consumption of the entire processor relative to a baseline with a well-performing hybrid load-value predictor.
