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

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

The Next Steps
By Aveek Sarkar - 10 May, 2012 - Comments: 0

By Aveek Sarkar Remaining competitive in today’s semiconductor market means IC designers must meet performance, power and price targets for their design, regardless of the end application. Meeting these mutually conflicting goals requires enlisting the use of several architectural and design techniques, including three-dimensional (3D) or stacked-die architectures that can help meet perfo... » read more

LP Macros
By Luke Lang - 10 May, 2012 - Comments: 0

By Luke Lang Many designers have asked why CPF has the macro model commands while UPF/1801 does not. I will try to answer this question and explain the differences in both approaches. First, let’s briefly review CPF macro model. A CPF macro model describes the power interface of a macro cell, which could be a complex cell (pad cell), an IP block (memory), or a hardened block (ARM core). F... » read more

Intel’s Hot New Tri-Gate Processors
By Barry Pangrle - 10 May, 2012 - Comments: 0

By Barry Pangrle Intel announced its newest third-generation Core processors on April 23rd. There has been much anticipation surrounding these new chips from Intel, largely because of their new 22nm tri-gate process technology used to fabricate these devices. Figure 1, from the presentation entitled, “Intel’s Revolutionary 22nm Transistor Technology,” by Mark Bohr and Kaizad Mistry, s... » read more

Standards: Too Many or Not Enough?
By Kiran Vittal - 10 May, 2012 - Comments: 0

Many of you are familiar with the Betamax versus VHS format wars in the late 1980s. If you’re not old enough to remember that one, you’ll remember HD DVD versus Blu-ray. In each of these cases, there was a clear winner. Semiconductor design has these format wars, too. The problem is that there is rarely a clear winner and worse, sometimes we miss the standard altogether. There are tw... » read more

The Bigger Problem
By Bhanu Kapoor - 10 May, 2012 - Comments: 0

By Bhanu Kapoor Getting power management features already built into chips to be fully utilized is indeed the bigger problem. The features here refer to hooks provided by power management techniques such as voltage and frequency scaling, power gating, and threshold voltage scaling. There is no doubt that these features have helped a lot in optimizing power consumption. But they are mainly a... » read more

Mixed-Signal Integration Drives Platform Chips
By Ann Mutschler - 10 May, 2012 - Comments: 0

Not only are there low-power challenges with just about every design today, there are also very interesting issues concerning integration of mixed-signal onto chips. As chips are get bigger and more costly to develop, many companies are turning to platform chips that can be used in a smartphone and in a tablet with slightly different twists in the functionality of that platform chip because ... » read more

Reliability Verification For Smart ICs
By Arvind Vel - 05 Apr, 2012 - Comments: 0

By Arvind Shanmugavel The electronic brains behind today’s advanced systems are smart ICs, paving the way for consumer electronics, energy, biomedical, automotive and avionics industries. Power efficiency and system integration are keys to the success of these smart systems. The IC industry has swiftly responded with state-of-the-art low-power techniques and chip integration initiatives f... » read more
