Low Power Design: From Soup to Nuts

Mary Jane Irwin and Vijaykrishnan Narayanan
Department of Computer Science and Engineering
The Pennsylvania State University

1. ABSTRACT

Power consumption has emerged as a significant design constraint, along with throughput, area, and accuracy (operand precision), in computing systems. This concern has been accelerated by the growing popularity of wireless systems, but exists even in high performance, tethered systems since circuit cooling requirements affect packaging costs and circuit reliability. Next generation designers forecast that future microprocessors could consume hundreds of watts unless further advances are made in low power design. Power optimizations can be made at the circuit level, gate level, architecture level, and software level. This tutorial will cover this entire design spectrum - from "soup to nuts" - concentrating in particular on architecture and software power design issues and t switching activity is largely determined by the software running on the system.

2. ASSUMED ATTENDEE BACKGROUND

Assumed attendee background is a intermediate to advanced background in computer architecture design, a beginner to intermediate background in the area of compiler optimizations, and a beginner background in circuit level design.
