In this paper, we introduce a simple hardware mechanism supporting non-blocking loads in conjunction with lockup-free caches to hide memory latencies in high-performance processors. The cache and processor cooperate on load misses so that the overall complexity of the non-blocking mechanisms in the cache and in the processor is greatly reduced. We use detailed simulations to evaluate the effectiveness of the architecture and of a simple compiler transformation at hiding miss latencies of up to… CONTINUE READING
