Spatio-temporal memory streaming

Recent research advocates memory streaming techniques to alleviate the performance bottleneck caused by the high latencies of off-chip memory accesses. Temporal memory streaming replays previously observed miss sequences to eliminate long chains of dependent misses. Spatial memory streaming predicts repetitive data layout patterns within fixed-size memory regions. Because each technique targets a different subset of misses, their effectiveness varies across workloads and each leaves a significant fraction of misses unpredicted.
