Phase-Change Memory (PCM) has emerged as a promising low-power candidate to replace DRAM in main memory. Hybrid memory architecture comprised of a large PCM and a small DRAM is a popular solution to mitigate undesirable characteristics of PCM writes. Because PCM writes are much slower than reads, writebacks from the last-level cache consume a large portion of memory bandwidth, and thus, impact performance...
The current trend to move from homogeneous to heterogeneous multi-core systems promises further performance and energy-efficiency benefits. A typical future heterogeneous multi-core system includes two distinct types of cores, such as high performance sophisticated (``large'') cores and simple low-power (``small'') cores. In those heterogeneous platforms, execution phases of application threads that...
