Steep-Slope Devices: From Dark to Dim Silicon

Although the superior subthreshold characteristics of steep-slope devices can help power up more cores, researchers still need CMOS technology to accelerate sequential applications, because it can reach higher frequencies. Device-level heterogeneous multicores can give the best of both worlds, but they need smart resource management to realize this promise. In this article, the authors discuss device-level heterogeneous multicores and various resource-management schemes for reaching higher energy efficiency.
