“All I was doing was trying to get home from work.” – Rosa Parks

Bugs are an inevitability, but they’re especially embarrassing when your customer finds them before you do. All things being equal, it would be better if your devices notified you of a bug instead of your customers calling to complain that their shiny and expensive new device just tipped over.

Once you confirm that the bug is real, the next steps are finding and fixing it, and then somehow … Read More → "When the Bugs Find You"

Ultimate Guide to Switch Debounce (Part 6)

by Max Maxfield

April 2, 2020

Way back in the mists of time, when I was bright-eyed and bushy-tailed, as I penned the first words in this quest to explore the topic of switch bounce and debounce, I actually thought it would take only one, perhaps two, columns. Sad to relate, as the days grew into weeks and the weeks grew into months, I grew into a much sadder and wiser man. … Read More →

Creating Innovation in a Vacuum

Unique Device Technology Avoids Complicated Semiconductor Techniques

by Jim Turley

April 1, 2020

“No matter where you go, there you are.” – Buckaroo Banzai

A new venture-backed startup is developing disruptive technology that promises to upend long-cherished beliefs about electronics, semiconductors, manufacturing processes, and power consumption. It eliminates or minimizes many of the expensive and time-consuming steps used in today’s billion-dollar semiconductor fabs, while also shifting power consumption numbers by several orders of magnitude.

Backed by Silicon Valley venture-capital firms as well as private investors, the new company promises to heat up the market while … Read More → "Creating Innovation in a Vacuum"

HLS Powers AI Revolution

Will Inference Finally Mainstream HLS?

by Kevin Morris

March 31, 2020

I started working in high-level synthesis (HLS) in 1994 which, assuming my math is correct, was 26 years ago. In those early days, we referred to the technology as “behavioral synthesis” because it relied on analyzing the desired behavior of a circuit in order to create a structural description rather than simply converting from a higher-level structural description to a lower-level one.

HLS promised to replace thousands of lines of detailed RTL code with a few dozen lines of behavioral description as the primary design entry method. It brought the ability to … Read More → "HLS Powers AI Revolution"

“Phone home.” – E.T., the extraterrestrial

Bigger, better, higher, faster. That’s the usual mantra for electronics innovation, where standing still is the same as running backwards. But there’s something to be said for slowing down and smelling the proverbial roses. It’s relaxing. And it’s cheap.

Amid all the expensive and incessantly hyped build-out of 5G wireless networks (including some … Read More → "IoT Connectivity on the Cheap"

Worried About Your SSD Data? Virtium Has You Covered!

by Max Maxfield

March 26, 2020

I’ve been thinking a lot about the impermanence of data recently. A lot of my own documents and images that used to travel through time with me in the physical realm* – photographs, letters, journals – seem to have become lost in the mists of the past (*as opposed to using my time machine, which is currently hors de combat — you simply cannot lay your hands on spare parts in the time and place I currently hang my hat).

In some respects, the situation is worse in the case of computers, where things can be lurking … Read More → "Worried About Your SSD Data? Virtium Has You Covered!"

Setting Sensible Standards for IoT

GlobalPlatform Takes on the Daunting Task of Governing the Ungovernable

by Jim Turley

March 24, 2020

“The majority of meetings should be discussions that lead to decisions.” – Patrick Lencioni

Setting standards must be lonely work. You meet, you discuss, you weigh options, and you write up prescriptions. And then you wait, hoping the industry will follow your lead and take your advice. If they do, great. And if not? Well, there’s always another hill to climb.

One group that’s been doing this work for 20-odd years is Read More → "Setting Sensible Standards for IoT"

What Is bfloat16, Anyway?

New Floating-Point Format is Suddenly Popular for Machine Learning

by Jim Turley

March 23, 2020

“If you ever hear yourself saying, ‘I think I understand this,’ that means you don’t.” — Richard Feynman

Nothing about AI or machine learning is intuitive. Maybe that’s the point.

An example is the sudden rise in popularity of something called “bfloat16,” a new way of representing numbers that holds magical appeal to AI/ML programmers – and, therefore for chipmakers as well. So, let’s look at bfloat16 for beginners. If you’re an experienced programmer, skip ahead.

Ultimate Guide to Switch Debounce (Part 5)

by Max Maxfield

March 19, 2020

Just to ensure we’re all tapdancing to the same drumbeat before we leap into the fray with gusto and abandon, let’s briefly remind ourselves that in Part 1 of this miniseries we introduced the concept of switch bounce. Later, in Part 2, we took a deeper dive into the bouncing associated with … Read More → "Ultimate Guide to Switch Debounce (Part 5)"

Estimating Power Before You Start

Wisebatt Tool Predicts Power Consumption Before Hardware is Ready

by Jim Turley

March 18, 2020

“Power corrupts. PowerPoint corrupts absolutely.” – Edward Tufte

Want to know how much energy your new battery device will consume? The answer may be in Paris.

Wisebatt is an 11-person startup based in the French capital city, and they’ve produced a tool that estimates battery life and power consumption with remarkable accuracy. Remarkable, because you don’t have to give it very much information to go on. … Read More → "Estimating Power Before You Start"
