| Abstract: | As more transistors are integrated onto bigger die, an on‐chip multiprocessor will become a promising alternative to the superscalar microprocessor that dominates today's microprocessor marketplace. This paper describes key parts of a new on‐chip multiprocessor, called Raptor, which is composed of four 2‐way superscalar processor cores and one graphic co‐processor. To obtain performance characteristics of Raptor, a program‐driven simulator and its programming environment were developed. The simulation results showed that Raptor can exploit thread level parallelism effectively and offer a promising architecture for future on‐chip multiprocessor designs. |
