Abstract

Chip multiprocessors have recently expanded from an active area of research to a hot product area. If Moore's law continues to apply in the chip multiprocessor era, we can expect to see a geometrically increasing number of cores with each advance in feature size. A critical question in CMPs is the size and strength of the replicated core. Many server applications focus primarily on throughput per cost and power. In reality, application needs are not always so simply characterized, and many types of applications can benefit from either the speed of a large core or the efficiency of a small core. Thus, the authors believe the best choice in core complexity is a heterogeneous chip microprocessor with both high- and low-complexity cores.
