From single core to multi-core

Abstract

In the past, processor design trends were dominated by increasingly complex feature sets, higher clock speeds, growing thermal envelopes and increasing power dissipation. Recently, clock speeds have tapered and thermal and power dissipation envelopes have remained flat. However, the demand for increasing performance continues which has fueled the move to integrated multiple processor (multi-core) designs. This paper discusses this trend towards multi-core processor designs, the design challenges that accompany it and a view of the research required to support it.
