Outbound Power Management
By Srikanth Jadcherla - 15 Oct, 2015 - Comments: 0

Many years ago when I first suggested that we should do platform-level power instead of focusing on the CPU, I was considered somewhat of a heretic. Yet, within 10 to 15 years of that recommendation, most of the platforms around us have moved to that method using operating system functions to keep track of the overall power, battery life, etc. As we move into the era of billions of connected de... » read more

Raising The IQ Of Your MEMS-Based IC Design Flow
By Nicolas Williams - 15 Oct, 2015 - Comments: 0

By Nicolas Williams and Qi Jing Internet of Things (IoT) applications depend on smart objects that interact with the real world. So your IoT project is likely to contain ICs that integrate micro electro-mechanical systems (MEMS), such as accelerometers, pressure sensors, motors, and microphones that acquire data for analysis. These projects are finding their way into automobiles, phones, and... » read more

Is it Hot? Ask Joules
By Paul McLellan - 15 Oct, 2015 - Comments: 0

Over the last decade it has become clear that power reduction techniques involving different parts of the chips would become more important than they had historically. In 2G cell phones everything except the real-time clock could be turned off when the phone was not in use. Pre-smartphones, a phone was either making a call (or texting, gaming, etc.) or it was off. In fact, a cell phone can’t ... » read more

Making Cars Better
By Jérôme Toublanc - 11 Sep, 2015 - Comments: 0

The automotive industry, with its double-digit growth, is a very attractive market for equipment manufacturers. This growth is explained not only by the increasing number of cars produced for the Asia market, but also by the shift of basic customer expectations for things such as more hybrid and electrical vehicles, more sophisticated infotainment requirements, and more high-end features. O... » read more

A Strategy For Designing For Power With FinFETs
By Anand Iyer - 11 Sep, 2015 - Comments: 0

Recently Qualcomm announced their new SnapDragon processor 820, which was designed using finFET technology. They showed some amazing results, such as 2X improvement in performance and 2X improvement in power compared to 28nm designs. Previously, when ARM announced their A72 processors in finFET, they too had claimed 3.5X improvement in power compared to 28nm designs. But can designers expect... » read more

Which Memory Type Should You Use?
By Loren Shalinsky - 10 Sep, 2015 - Comments: 1

I continue to get besieged by statements in which memory “latency” and “bandwidth” get misused. As I mentioned in my last blog, latency is defined as how long the CPU needs to wait before the first data is available, while bandwidth is how fast additional data can be “streamed” after the first data point has arrived. Bandwidth becomes a bigger factor in performance when data is stor... » read more

Two Constraints-Based Techniques To Address Power-Related Challenges In SoC Design
By Christine Young - 10 Sep, 2015 - Comments: 0

Power scheduling, power integrity targets, voltage drop—these are just a few of the power-related challenges you’re no doubt managing in your SoC designs. There aren’t any easy answers, but there are some emerging—and promising—techniques. Two such techniques, according to University of Toronto Professor Farid Najm, are constraints generation and constraints-based verification. “... » read more

Thermal And Power Considerations In Designing For The Developing World
By Brian Fuller - 10 Sep, 2015 - Comments: 0

Engineers designing for emerging markets confront fascinating challenges. Take data centers for developing societies. Most of these systems are in remote locations, exposed to the elements, with limited power, save for the sun. How do you deal with rain, rust, durability? How do you prevent members of the animal kingdom sauntering by and chewing on your system? These are some of the intri... » read more

How To Speed Up Networking Design Verification
By Lauro Rizzatti - 10 Sep, 2015 - Comments: 0

The enormous growth of the Internet of things (IoT) has an enormous impact on network providers. After all, without the underlying network infrastructure, there would be no IoT. One consequence has been a significant increase in the number of Ethernet ports on networking devices. Today, Ethernet switches and routers reach 256 ports (by year’s end that number will increase to 1024 ports), a... » read more

Shift In Focus For Low Power Design
By Alan Gibbons - 10 Sep, 2015 - Comments: 0

The increased levels of interest we have seen over the last couple of years in system-level power modeling and energy-aware system-level design methodology, coupled with broad participation in the associated industry standard activities around system level power, gives us a clear indication that a shift in focus for low-power design is taking place. Our attempts to deliver energy-efficient high... » read more
