Reaching For ROI
By Ann Mutschler - 17 Feb, 2016 - Comments: 0

The simplest way to assess power and performance ROI of a chip design is to ask if the chip works and whether it meets the design specifications. But chips can be used in very different ways, and a single chip may have a number of operational modes, so that formula isn't so clear anymore. "Preventing failures is the No. 1 priority when it comes to ROI," said Aveek Sarkar, vice president of p... » read more

Adventures In Assembly
By Ann Mutschler - 11 Feb, 2016 - Comments: 0

With so few [getkc id="81" kc_name="SoC"] designs — if any — today designed completely new from the ground up, the assembly task is an extremely important one to get right. [getkc id="43" kc_name="IP"] components must be put together optimally and efficiently to perfectly match the application requirements, which is complex and intricately nuanced. How companies approach IP varies signif... » read more

Brain-Inspired Computing

Approaching power/performance tradeoffs from an architectural perspective is essential given the complexities of today’s SoCs. And beyond some traditional techniques that I discussed in a recent article, Bernard Murphy, CTO at Atrenta mentioned that there is currently a lot of buzz about using non-Von Neumann architectures — especially for recognition functions (voice, image and text). ... » read more

Capturing Performance
By Ann Mutschler - 14 May, 2015 - Comments: 0

The challenge of working out the best performance for a given power budget is not a new one, but in many power-sensitive applications, the balance is tricky and requires sophisticated techniques. This is especially true in the media processor market where many systems companies are held back by power, energy and thermal issues. “It's really not a battery problem, it's a thermal problem... » read more

The Power Game
By Ann Mutschler - 11 Apr, 2013 - Comments: 0

By Ann Steffora Mutschler Semiconductor engineering teams always have focused on stepping up performance in new designs, but in the mobile, GPU and tablet markets they’re finding that maintaining the balance between higher performance and the same or lower power is increasingly onerous. The reason: Extreme gaming applications can create scenario files that cause dynamic power consumpt... » read more

Tradeoffs On The Fly
By Ed Sperling - 17 Jan, 2013 - Comments: 0

By Ann Steffora Mutschler With classical bulk planar technology no longer shrinkable, the industry has been honing in on new ways to continue some scaling, achieve extra speed or better power while minimizing leakage. “To overcome the limits [of bulk planar technology] we need a different solution,” explained Giorgio Cesano, technology R&D marketing director at STMicroelectron... » read more

Keeping The Balance
By Ed Sperling - 13 Sep, 2012 - Comments: 0

By Ann Steffora Mutschler The brains of datacenters today are more powerful than ever due to technology advancements in chip architectures and in manufacturing processes that allow more processing power thanks to Moore’s Law. But knowing exactly how and where to configure the processors and cores for optimum throughput and performance within a certain power budget raises a number of qu... » read more
