1 Motivation The performance gap between processor and main memory speed, called memory wall, is serious problem especially in High Performance Computing (HPC). This memory wall problem is addressed by two factors , large memory access latency and lack of memory throughput. There have been proposed many techniques for tolerating memory access latency,(More)
In order to overcome performance degradation caused by performance disparity between processor and main memory, there have been proposed several new VLSI ar-chitectures which have software controlled on-chip memory in addition to the conventional cache. However, users must specify data allocation/replacement on software controlled on-chip memory and data(More)
Recently, power-performance (performance per uniform power consumption) has become a more important factor in modern high-performance microprocessors. In processor design, it is a well-known that off-chip memory access has a large impact on both performance and power consumption. On-chip memory is one solution for this problem, so that many processors such(More)
