Power-Performance-Thermal


People like me are challenged in the culinary department. We believe that all we have to do is put the meat, vegetables, sauce and everything else in the recipe into the crockpot and a few hours later, out comes dinner. We (desperately) believe that we can dump the ingredients into a Ninja blender and get a healthy, tasty shake in a few minutes. (I have been politely informed that it is NOT the... » read more

2026: I Can Only Imagine…


It was fun to see all of the new products that were rolled out this year at CES. It got me thinking about how much technology has advanced in the past 10 years. In 2006, the iPhone was still a year away from being introduced and we hadn’t discovered tablets yet. The Internet wasn’t mobile and the cloud was still something in the sky. Never mind Fitbits, smart watches, augmented reality or a... » read more

Remove The Bus From Your Embedded System


For many years, the 8-bit microcontroller has been the workhorse of embedded systems. Design teams favor the size and power benefits that a tightly coupled processor, such as the 8051 microcontroller, brings to their designs. The compact and ultra-low power 8-bit architecture improves battery life and reduces bill-of-material costs. However, embedded systems increasingly require higher perfo... » read more

Stop Getting Burned By Power Consumption Surprises


Very rarely these days do we get silicon back and find that we have missed our timing or test constraints by a significant margin. We have robust EDA tools, libraries and design methodologies in place to ensure that we can cleanly signoff against these constraints. However, we do continue to see too many unfortunate “surprises” in silicon related power (energy) consumption and thermal issue... » read more

Outbound Power Management


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

Shift In Focus For Low Power Design


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

Using Automotive-Ready IP To Accelerate SoC Development


IP suppliers play a key role in the automotive supply chain to enable high-performance advanced driver assistance system (ADAS) SoCs. Vision-based SoCs may contain a high amount of third-party IP to implement the key embedded vision, sensor fusion, multimedia, security and advanced connectivity functions. And while IP suppliers have permeated the semiconductor ecosystem for consumer, mobile, PC... » read more

Interface IP Subsystems Speed TTM


Interface protocol specifications start out simply, handling off-chip communication for SoCs. As more companies get involved in the specifications, each company adds features to address their market segments. Each new version of the protocol specification offers new features and increased speed, and the protocols are often overhauled to work at higher speeds and improve performance for applicat... » read more

Confidence Is The New Verification


Everywhere around us the devices we use are getting connected to each other digitally. New devices that sense and quantify the parameters we need to make decisions are also being created. It is estimated that 26 billion connected devices will be installed by 2020, or roughly four per person on the planet! The whole purpose of the connected device is to observe/report and control remotely, of... » read more

One PHY Does Not Fit All


Consumers expect their battery-operated mobile devices to be faster, smaller and more reliable while providing greater functionality at a reduced cost. Most of all, consumers demand longer battery life and 24/7 access to data. To meet these demands, consumer system-on-a-chip (SoC) designers must make tradeoffs between features, performance, power and cost. Enterprise SoC designers have their... » read more
