description <!--HTML--><p align="justify">Technology forecasts indicate that device scaling will continue well into the next decade.&nbsp; Unfortunately, it is becoming extremely difficult to harness this increase in the number of transistors&nbsp;into performance due to a number of technological, circuit, architectural, methodological and&nbsp; programming challenges.</p><p align="justify">In this talk, I will argue that the key emerging showstopper is power.&nbsp; Voltage scaling as a means to maintain a constant power envelope with an increase in transistor&nbsp; numbers is hitting diminishing returns. As such, to continue riding the Moore's law we need to look&nbsp; for drastic measures to cut power.
