One-On-One: Mike Muller
By Ed Sperling - 13 Oct, 2014 - Comments: 0

SE: What happens with memory, where access is more localized? Muller: Hybrid memory cube is one approach. HBM is another. ARM is chairing an IEEE standards group for a next-gen memory interface to make sure we build memories that fit mobile as well as networking and classic servers. Whereas in the past, memories were driven from the performance, we need to make the power scales with the band... » read more

New Architectures Redefining The Data Center
By Ed Sperling - 26 Sep, 2013 - Comments: 0

By Ed Sperling The cost of powering and cooling data centers, coupled with a better understanding of how enterprise-level applications can utilize hardware more effectively, are spawning a new wave of changes inside of data centers. Data centers are always evolving, but in this sector that evolution is deliberate and sometimes painstakingly slow. In fact, each major shift tends to last a de... » read more

Coherently Incoherent: Dealing With Complexity
By Frank Ferro - 25 Oct, 2012 - Comments: 0

By Frank Ferro I was a bit frustrated this weekend after installing a digital light timer—yes a light timer. As an engineer this should be no big deal, and for the most part, I installed it without shocking myself or other major problems. This timer had all the bells and whistles. It knows about time zones, adjusts daily for dawn and dusk. It even adjusts for daylight savings time. The probl... » read more

Experts At The Table: Coherency

Revisiting Moore’s Law
By Ed Sperling - 09 Aug, 2012 - Comments: 0

Moore’s Law was predicted to end at 1 micron. It was predicted to die off twice by Gordon Moore himself. And it has vacillated between 18 and 24 months on at least a couple of occasions since it was first introduced in 1965. From a technology perspective, there is no reason to assume it will ever die. It has gone from microns to nanometers and it can continue well into the picometer range.... » read more
