On-chip DRAM cache has the advantage of increased cache capacity that may alleviate the memory bandwidth problem. Recent research has demonstrated the benefits of high capacity on-chip DRAM cache that leads to reduced off-chip accesses. However, state-of-the-art has not taken into consideration the cache access patterns of concurrently running heterogeneous applications that can cause inter-core cache contention. The authors therefore propose an adaptive bank mapping policy in response to the diverse requirements of applications with different cache access behaviors that - as a result - reduces inter-core cache contention in DRAM-based cache architectures.
