LP Macros 2
By Luke Lang - 14 Jun, 2012 - Comments: 0

By Luke Lang Last month, I compared the CPF macro model with LP attributes in the Liberty model. The CPF macro model was developed when Liberty had very little LP attributes to support LP designs. Even today, Liberty still lacks LP attributes to describe some of the common power intent in LP designs. One example is an LP IP block with internal power switches and shutoff domains. Because mos... » read more

New Challenges, New Name
By Ed Sperling - 14 Jun, 2012 - Comments: 0

As you’ll notice today, we’ve changed our name from Low Power Engineering to Low-Power/High-Performance Engineering. We don’t take name changes lightly—we've been discussing this in depth with readers, sponsors, and researchers for the past six months. The almost universal conclusion is there is a big shift underway in the semiconductor industry today, and our new logo is a better refle... » read more

Low Power Everywhere
By Kiran Vittal - 14 Jun, 2012 - Comments: 0

By Kiran Vittal School is over for my kids and the summer holidays are here. We are planning to make minor modifications to our home, which includes installation of recessed lights. LED light bulbs are all over the place in home appliance stores and they claim 85% savings in energy costs with a life span of 50,000 hours. The cost of these LED bulbs is five to six times the cost of your average... » read more

Experts At The Table: Black Belt Power Management
By Ann Mutschler - 14 Jun, 2012 - Comments: 0

By Ann Steffora Mutschler With approximately 80% of SoC content reused from past designs or brought in from internal and external IP sources, a significant part of a design engineer’s job today is writing glue logic and verifying to make sure the integrated system communicates as dictated by the specification. Integration challenges continue to mount with the increasing amount of black ... » read more

Efficiency Vs. Accuracy
By Barry Pangrle - 14 Jun, 2012 - Comments: 0

By Barry Pangrle If all you have is a hammer, everything looks like a nail. I wrote an article, Power vs. Accuracy, last year that discussed tradeoffs between power and accuracy for different applications. It turns out that for a number of processing applications, if every bit isn’t perfect, the impact on the final result might not be all that great. Anyone performing financial analytical... » read more

Training The Next Gen For Low Power
By Ann Mutschler - 14 Jun, 2012 - Comments: 0

Reflecting on my time at this year's Design Automation Conference, I am quickly reminded that I work in the most fascinating industry I can think of. Having the opportunity to discuss deep technical low power design issues, forward-looking challenges as well as the business implications face to face with thought leaders is inspiring and invigorating. With the amount of brain power filling Mosco... » read more

Roundtable: DAC Retrospective
By Ed Sperling - 13 Jun, 2012 - Comments: 0

Is DAC really a design automation conference, or has it shifted to a design enablement conference due to rising complexity breaking down traditional barriers and silos? Low Power High Performance Engineering talks with Atrenta CTO Bernard Murphy about the changes. [youtube vid=Z_xBaRsC_Hs] » read more

Breaking the Barrier Again: Fab Equipment Spending Up in 2012; in 2013 to Reach an All-Time Record High
By Christian Dieseldorff - 11 Jun, 2012 - Comments: 0

Strong Improvement also Seen in Fab Construction By Christian Gregor Dieseldorff, SEMI Industry Research & Statistics (June 1, 2012) Breaking the barrier into positive growth for 2012, the end-of-May edition of the World Fab Forecast shows improved growth in fab equipment spending this year — at US$ 39.5 billion, a two percent year-over-year (YoY) increase.  For 2013, fab equipment... » read more
