抄録(英) Many of us in the field of ultra-low-V_
processors experience difficulty in assessing the sub/near threshold circuit techniques proposed by earlier papers. This paper investigates three major pitfalls which are often not appreciated by researchers when claiming that their circuits outperform others by working at a lower V_
with a higher energy-efficiency. These pitfalls include: i) overlook the impacts of different technologies and different V_
definitions, ii) only emphasize energy reduction but ignore severe throughput degradation, or expect impractical pipelining depth and parallelism degree to compensate this throughput degradation, iii) unrealistically assume that memory's V_
and energy could scale as well as standard cells. Therefore, the actual energy benefit from using a sub/near threshold V_
can be greatly overestimated. This work provides some design guidelines and silicon evidence to ultra-low-V_
systems. The outlined pitfalls also shed light on future directions in this field.
