Speed Demons
By Barry Pangrle - 01 Dec, 2011 - Comments: 0

By Barry Pangrle For extreme world record performance levels, the required power levels are also typically extreme. It’s that age-old battle against diminishing returns to squeeze out every last drop of performance versus practical limits and wallets. For example, a top fuel dragster can consume about six gallons of fuel for a quarter-mile run down the strip. As has previously been shown ... » read more

Innovation At The Core
By Barry Pangrle - 03 Nov, 2011 - Comments: 0

By Barry Pangrle A number of next-generation ARM-based multi-core systems are starting to show up in the press. Nvidia has released information on its upcoming Tegra 3 (also known as “Kal El”). At last week’s ARM Techcon in Santa Clara, ARM gave several presentations around its Cortex-A7 (Kingfisher) and Cortex-A15 (Eagle) architectures and collectively about its big.LITTLE strategy. Qua... » read more

Intel’s Claremont Near-Threshold Voltage IA Core
By Barry Pangrle - 06 Oct, 2011 - Comments: 0

By Barry Pangrle Intel announced many new technologies at its recent Intel Developer Forum (IDF) held from Sept. 13-15 in San Francisco, but the one announcement that jumped out at me was the unveiling of its work on a near-threshold voltage (NTV) processor named “Claremont.” For this exercise, Intel chose an older Pentium design to help minimize the number of variables the engineers would... » read more

Interconnect Power II
By Barry Pangrle - 08 Sep, 2011 - Comments: 0

Barry Pangrle After submitting last month’s blog, I read a very interesting article by Deepak Sekar analyzing Intel’s 22 nm FinFET technology versus a hypothetical planar 22nm CMOS technology. Beyond the advantages of being able to use a 140 mV reduction in the supply voltage for the trigate technology, Deepak did a breakdown analysis for the predicted power across a representative micropr... » read more

Interconnect Power
By Barry Pangrle - 11 Aug, 2011 - Comments: 0

By Barry Pangrle Applied Materials announced its latest version of nano-porous low-k dielectric technology called Black Diamond 3 last month at Semicon West. What really caught my ear though was the marketing claim that 1/3 of total chip power consumption (really energy) is in the interconnect. I thought about this a bit, and certainly for some designs this seemed to easily be quite po... » read more

Building A Better CMOS FET
By Barry Pangrle - 21 Jul, 2011 - Comments: 0

By Barry Pangrle SEMICON West was held last week in San Francisco and I had the opportunity to attend the Emerging Architectures session. Serge Biesemans, vice president of process technology at Imec, gave a nice overview presentation on FinFETs. From a power and performance standpoint, we’ve seen some early pre-production information released from Intel that I briefly discussed here. Serge�... » read more

The Tough Metric: Energy-Efficiency
By Barry Pangrle - 16 Jun, 2011 - Comments: 0

By Barry Pangrle Jem Davies, fellow and vice president of technology at ARM, gave a keynote address on Computing Power and Energy-Efficiency Tuesday morning at the AMD Fusion Developer Summit in Bellevue, Washington. His scheduled appearance at the summit led to much speculation and rumor a while back, especially within the context of the ARM versus x86 battle for market share in the tablet ar... » read more

Intel’s New Machine
By Barry Pangrle - 12 May, 2011 - Comments: 0

By Barry Pangrle Power is one of those product characteristics that touches on every phase of the design and verification process all the way from the system architecture down to the fabrication process used for the actual IC implementation. In this month’s blog we take a look at process technology and in this case, it appears to be the case that the technology rich are getting richer. On... » read more

Emulation Power
By Barry Pangrle - 14 Apr, 2011 - Comments: 0

By Barry Pangrle Power budgets and the characteristics of the underlying process technologies have limited the clock speeds of the processors often found in large compute farms for simulation over the past six years, but the designs under test have followed Moore’s Law and have kept growing larger at an exponential rate. Processor designers have added more cores per chip to increase the p... » read more

Core Power
By Barry Pangrle - 17 Mar, 2011 - Comments: 0

By Barry Pangrle What type of core should I choose if I want to be really power-efficient? That’s an interesting question. The answer that a lot of people will hate to hear is that it depends. Probably the first question that needs to be answered is, what does power-efficient mean to you and how power-efficient do you really want to be? Most people can’t wait forever for a result to be ... » read more
