Energy considerations in multichip-module based multiprocessors

Abstract

Multichip modules permit highly efficient implementation of tiled architectures. If the tiles are implemented in submicron CMOS, extremely highly computation rates can be achieved, but power dissipation becomes the principal factor limiting achievable levels of integration and performance. Some examples of tiled architectures are described. The feasibility and advantages of reduced voltage operation for reducing energy per operation in power constrained environments are discussed.<>
