Energy efficient CMOS microprocessor design

Concern over power dissipation in CMOS microprocessors is increasing, not just for portable battery-based applications, but also for performance-driven designs, where power may soon displace silicon area as the principal design constraint. Traditional ...

Measuring energy proportionality accurately and understanding the reasons for disproportionality are critical first steps in designing future energy-efficient servers. This article presents two metrics—linear deviation and proportionality gap—that let ...

We present and evaluate seven techniques to reduce energy dissipation for accesses to a processor register file: modified storage cell avoids bitline discharge for zero bits, precise read control avoids fetching unused operands, latch clock gating ...
