Near-Threshold Computing Gets A Boost
By Brian Bailey - 25 Jul, 2022 - Comments: 0

Near-threshold computing has long been used for power-sensitive devices, but some surprising, unrelated advances are making it much easier to deploy. While near-threshold logic has been an essential technique for applications with the lowest power consumption, it always has been difficult to use. That is changing, and while it is unlikely to become a mainstream technique, it is certainly bec... » read more

On-Chip Monitoring Of FinFETs
By Ed Sperling - 25 Jul, 2018 - Comments: 0

Stephen Crosher, CEO of Moortec, sat down with Semiconductor Engineering to discuss on-chip monitoring and its impact on power, security and reliability, including predictive maintenance. What follows are excerpts of that conversation. SE: What new problems are you seeing in design? Crosher: There are challenges emerging for companies working on advanced nodes, including scaling and trans... » read more

Near-Threshold Issues Deepen
By Ann Mutschler - 14 Jun, 2018 - Comments: 0

Complex issues stemming from near-threshold computing, where the operating voltage and threshold voltage are very close together, are becoming more common at each new node. In fact, there are reports that the top five mobile chip companies, all with chips at 10/7nm, have had performance failures traced back to process variation and timing issues. Once a rather esoteric design technique, near... » read more

Tech Talk: Near-Threshold Power
By Ed Sperling - 13 Nov, 2017 - Comments: 2

Lauri Koskinen, CTO and founder of Minima Processor, and Ron Moore, vice president of marketing at ARM, talk about near-threshold computing, dynamic power and margining, and how these techniques can extend battery life and reduce energy consumption. https://youtu.be/BhiNFe4NYQU » read more

Reaching The Power Budget
By Ann Mutschler - 11 Aug, 2016 - Comments: 1

Everything related to power in chip design today is a big deal—and it’s just getting bigger. Meeting the power budget is becoming harder at each new node, but it's also becoming difficult in a number of new application areas at existing nodes. That's a big problem because [getkc id="108" kc_name="power"] is now considered a competitive advantage in many markets. It's also one of the most... » read more

Near-Threshold Computing
By Brian Bailey - 16 Jun, 2016 - Comments: 2

The emergence of the Internet of Things (IoT) has brought a lot of attention to the need for extremely low-power design, and this in turn has increased the pressure for voltage reduction. In the past, each new process node shrunk the feature size and lowered the nominal operating voltage. This resulted in a drop in power consumption. However, the situation changed at about 90nm in two ways. ... » read more

New Approaches To Low Power Design
By Ann Mutschler - 14 Dec, 2015 - Comments: 1

While Moore's Law continues to drive feature size reduction and complexity, a whole separate part of the industry is growing up around vertical markets in the IoT. While these two worlds may be different in many respects, they share one thing in common—low power design is critical to success. How engineering teams minimize power in each of these markets, and even within the same market, ca... » read more

2016 And Beyond
By Krishna Balachandran - 10 Dec, 2015 - Comments: 0

Greek mythology and Roman history are replete with soothsayers, some of whom got it right and others wrong. Cassandra was cursed that her predictions wouldn’t be believed, even though she predicted the Trojan horse. Caesar’s soothsayer predicted the demise of Julius Caesar during the Ides of March, which Caesar himself was skeptical about, but indeed he was murdered before the Ides passed. ... » read more

Memory Choices Grow
By Ed Sperling - 24 Nov, 2015 - Comments: 1

Memory is becoming one of the starting points for SoC architectures, evolving from a basic checklist item that was almost always in the shadow of improving processor performance or lowering the overall power budget. In conjunction with that shift, chipmakers must now grapple with many more front-end decisions about placement, memory type and access prioritization. There are plenty of rules ... » read more

Power Breaks Everything
By Ed Sperling - 15 Jul, 2015 - Comments: 2

The emphasis on lowering power in everything from wearable electronics to data centers is turning into a perfect storm for the semiconductor ecosystem. Existing methodologies need to be fixed, techniques need to be improved, and expectations need to be adjusted. And even then the problems won't go away. In the past, most issues involving power—notably current leakage, physical effects such... » read more
