Peripheral Memory: A Technique for Fighting Memory Bandwidth Bottleneck

Memory bottleneck has always been a major cause for limiting the performance of computer systems. While in the past latency was the major concern, today, lack of bandwidth becomes a limiting factor as well, as a result of exploiting more parallelism with the growing number of cores per die, which intensifies the pressure on the memory bus. In such an environment, any additional traffic to memor…
