Abstract
Digital circuits often have a critical path that runs
through a small subset of the component subblocks, but
where the path changes dynamically during operation. Dy-
namically resizable static CMOS (DRCMOS) logic is pro-
posed as a fine-grain leakage reduction technique that dy-
namically downsizes transistors in inactive subblocks while
maintaining speed in subblocks along the current critical
path. A 64-entry register free list and a 64-entry pick-two
arbiter are used to evaluate DRCMOS. DRCMOS is shown
to give a 50% reduction in total power for equal delay in a
70nm technology.
1 Introduction
Power has become one of the primary design constraints
