The Revolution Will Not Be Televised: It Will Be On Your Phone
By Rizwan Farooq - 07 Aug, 2014 - Comments: 1

The advent of smart devices has ushered in a revolution all over the world. The most widely used smart device is the mobile phone, which has radically changed the way we communicate. There are many other types of devices running 24/7 in our homes, hospitals, businesses, etc. No matter what kind of functionality smart devices have, they have one thing in common: they all consume energy. They ... » read more

GPUs Dominate (Again) The Green500 List
By Barry Pangrle - 16 Jul, 2014 - Comments: 0

The Green500 has released its latest list of the top 500 most energy-efficient Supercomputers. The top 17 are heterogeneous systems (systems that use more than one type of processor), with the top 15 systems all using NVIDIA Kepler K20 GPUs paired with Intel Xeon CPUs. Still at the top of the list is the Tokyo Institute of Technology GSIC Center’s TSUBAME-KFC, an oil-cooled Kepler powered ... » read more

LP SoC Design: Part 2
By Anand Iyer - 16 Jul, 2014 - Comments: 0

In my last blog I talked about why designers need to rethink their methodology for low-power design and also introduced gross and fine-grain low power techniques. In this blog I am going to compare and contrast these techniques. Low-power design techniques fall under two categories, gross and fine-grain. Gross techniques are not dependent on the design or the process. Techniques such as powe... » read more

IoT, A Market And Technology Set To Explode
By Zach Shelby - 10 Jul, 2014 - Comments: 0

While a fully-connected Internet of Things (IoT) world is still away off, an increasing number of devices are being built that can communicate with each other through wireless connections such as WiFi, Bluetooth, 6LoWPAN or Cellular. Current technology trends point toward a more seamlessly connected world, and for that to happen we must have cost-effective, low-power and highly connected dev... » read more

Server Memory: What Drives Its Growth?
By Loren Shalinsky - 10 Jul, 2014 - Comments: 2

I was recently reading several analyst reports that came out after the end of last quarter, and one caught my eye: "Gartner says Worldwide Server Shipments Grew 1.4%..." It caused me to wonder, how is it possible that server shipments only grow at modest rates, while the DRAM used in those servers is growing at significantly higher rates? Putting my search engine to use, I found a series of ... » read more

Using PCI Express L1 Sub-states To Minimize Power Consumption In Advanced Process Nodes
By Rita Horner - 10 Jul, 2014 - Comments: 0

The major sources of Internet traffic are shifting from wired to wireless and mobile devices. With the growing regulatory requirements and increased consumer pressure for more power-efficient products, designers need to better understand and optimize the power consumption of battery-operated devices. Power consumption of a portable device widely varies based on the user’s behavior and appl... » read more

FinFET Based Designs: Reliability Verification Implications
By Aveek Sarkar - 10 Jul, 2014 - Comments: 1

Over the past few months, I’ve discussed various challenges associated with finFET-based designs. We all know that finFET devices enable design teams to operate their chips at significantly lower supply voltages with a very tight control on leakage current. But to control the overall power within a tight power budget, the challenge shifts to how the logic design is managed such that the overa... » read more

Solar State Of Mind
By Ann Mutschler - 10 Jul, 2014 - Comments: 1

The dog days of summer seem an appropriate time to ponder all things solar while trying to stay cool. To this end, it’s rather encouraging to note more states are embracing solar as part of their energy mix and even the White House takes advantage of it. I was curious to know if there was a map of solar installations in the U.S., and sure enough, I found an interactive one on the website for ... » read more

Constraints Ubiquity: Impact On Managing Design Closure?
By Mark Baker - 10 Jul, 2014 - Comments: 0

By Mark Baker and Ravindra Aneja Maintaining completeness, correctness and consistency of design constraints is a challenge that is pervasive in the design flow. Multiple transformations, or touch points (as illustrated in the diagram below), exist during the design implementation stages. Additionally, there are parallel stages involving IP development and handoff resulting in SoC integration ... » read more

Amazon Fire And The Importance Of Interface Design
By Brian Fuller - 10 Jul, 2014 - Comments: 0

The flames have died down a bit from the red-hot coverage of the launch of the Amazon Fire smart phone, but the impact of the announcement lingers for me. Love or hate Amazon (I love the company), you have to tip your hat to CEO Jeff Bezos. He’s redefined smart phone design with this offering and in the process forced our industry to think about how we support system designers like Amazon. ... » read more
