ABSTRACT
<p>Editors' Note: Recent research has shown the potential benefits of subthreshold or near-threshold operation, which gives up a substantial degree of speed in order to reduce energy per operation. This is an excellent trade-off for many tasks, such as cyberphysical systems. This prolegomenon summarizes the benefits and challenges of subthreshold or near-threshold operation.</p>
INDEX TERMS
Prolegomena, subthrehold circuits, near-threshold circuits
