The IT Ecosystem and Global Competitiveness
I recently chaired a U.S. National Academies study on the issues surrounding the end of Dennard scaling and its implications for U.S. industry, defense capabilities and national security. The report, The New Global Ecosystem in Advanced Computing: Implications for U.S. Competitiveness and National Security, was just released. It is a cautionary tale about the Gordian…

Analog Computing: Time for a Comeback?
Use of the word “computer” conjures certain images and brings certain assumptions. One of them, so deeply ingrained that we rarely question it, is that computing is digital. It’s time to reconsider analog computing as an element of computer system design, particularly in a world of near threshold voltage designs, dark silicon, exascale computing and…

Surrounded By Opportunities
Our run of good luck is over. We need new, integrated design methodologies and rich collaborations that consider end-to-end design and capability. In many ways, this is a return to the past.
