Outline of Final Research Achievements

The objective of this study is to establish a smart memory subsystem architecture that can consider memory access behaviors of applications and effectively manage data in the memory hierarchy in terms of performance and power efficiency. In particular, we have developed 1) a low-power/high-bandwidth cache architecture, 2) a cache management policy with an on-line evaluation of the memory request behavior of an application for reducing its working set in the memory hierarchy, 3) a cache partitioning mechanism to protect performance-sensitive shared data for chip multicore processors, 4)a memory address mapping mechanism with the performance/performance optimization by using an online-estimation of memory access behavior.
