Steve Roddy, vice president of products for Arm’s Machine Learning Group, talks with Semiconductor Engineering about what different metrics actually mean, and why they can vary by individual applications and use cases. » read more

Less Food, More Thought
By Ed Sperling - 10 Oct, 2019 - Comments: 0

A trillion "things" are expected to be connected to the Internet sometime in the next decade. No matter how power-efficient these things are, they probably will require enough coin-sized lithium batteries to drain the world's supply of element No. 3 on the Periodic Table. They also will increase the demand for power everywhere, and that's even before tacking on electric vehicles, the edge, robo... » read more

Why DRAM Won’t Go Away
By Ed Sperling - 18 Sep, 2019 - Comments: 0

Semiconductor Engineering sat down to talk about DRAM's future with Frank Ferro, senior director of product management at Rambus; Marc Greenberg, group director for product marketing at Cadence; Graham Allan, senior product marketing manager for DDR PHYs at Synopsys; and Tien Shiah, senior manager for memory marketing at Samsung Electronics. What follows are excerpts of that conversation. Part ... » read more

Speed Returns As The Key Metric
By Ed Sperling - 08 Aug, 2019 - Comments: 0

For the foreseeable future, it's all about performance. For the past decade or so, power and battery life have been the defining characteristics of chip design. Performance was second to those. This was particularly important in smart phones and wearable devices, where time between charges was a key selling point. In fact, power-hungry processors killed the first round of smart watches. But ... » read more

Smart NiCs

Manish Sinha, strategic planning for marketing and business at Achronix, talks with Semiconductor Engineering about what’s changing in networking interface cards, how to get more performance out of these devices, and how much needs to be in hardware versus software. » read more

Multi-Layer Processing Boosts Inference Throughput/Watt
By Geoff Tate - 15 Apr, 2019 - Comments: 0

The focus in discussion of inference throughput is often on the computations required. For example, YOLOv3, a power real time object detection and recognition model, requires 227 BILLION MACs (multiply-accumulates) to process a single 2 Mega Pixel image! This is with the Winograd Transformation; it’s more than 300 Billion without it. And there is a lot of discussion of the large size ... » read more

GDDR6 – HBM2 Tradeoffs
By Ed Sperling - 10 Apr, 2019 - Comments: 0

Steven Woo, Rambus fellow and distinguished inventor, talks about why designers choose one memory type over another. Applications for each were clearly delineated in the past, but the lines are starting to blur. Nevertheless, tradeoffs remain around complexity, cost, performance, and power efficiency.   Related Video Latency Under Load: HBM2 vs. GDDR6 Why data traffic and bandw... » read more

Designing Networking Chips
By Ed Sperling - 07 Feb, 2019 - Comments: 0

Susheel Tadikonda, vice president of networking and storage at Synopsys, talks about what’s changed in the way networking chips are being designed to deal with a massive increase in data. One of those shifts involves software-defined networking, where the greatest complexity resides in the software. That also has a big impact on the entire design flow, from pre-silicon to post-silicon. htt... » read more

Edge Inferencing Challenges
By Ed Sperling - 10 Jan, 2019 - Comments: 0

Geoff Tate, CEO of Flex Logix, talks about balancing different variables to improve performance and reduce power at the lowest cost possible in order to do inferencing in edge devices. https://youtu.be/1BTxwew--5U » read more

Lies, Damn Lies, And TOPS/Watt
By Geoff Tate - 07 Jan, 2019 - Comments: 1

There are almost a dozen vendors promoting inferencing IP, but none of them gives even a ResNet-50 benchmark. The only information they state typically is TOPS (Tera-Operations/Second) and TOPS/Watt. These two indicators of performance and power efficiency are almost useless by themselves. So what, exactly, does X TOPS really tell you about performance for your application? When a vendor ... » read more
