When the Bugs Find You

“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 … Read More → "When the Bugs Find You"

Adventures in Satellite Security and The SpaceX Comfy Ride to the Moon

In this week’s podcast, we’ve got our eyes trained on the glittering skies. First up, we take a closer look at the spacecraft user manual for Starship, a next-generation launch vehicle currently being developed by SpaceX. We check out how Starship is going to be used, the details of its high-capacity the cargo hauler, and how Starship is going to get us to the moon in high-flying style. Also this week, we chat with Richard Jaenicke (Green Hills Software) about satellite security and vulnerability, how satellites can be hacked, and what solutions we need to implement at in order keep our satellites safely in orbit. … Read More → "Adventures in Satellite Security and The SpaceX Comfy Ride to the Moon"

Creating Innovation in a Vacuum

“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 … Read More → "Creating Innovation in a Vacuum"

HLS Powers AI Revolution

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.

As I've said before, I'm a hardware design engineer by trade, so I guess hardware solutions hold a certain appeal for me. It's like the old saying goes, "If your only tool is a hammer, everything starts to look like a nail" :-) I will be interested to hear your ...

I'm certainly all for teaching about switch bounce, as it's not obvious to the uninitiated that it actually occurs. I'm also all for teaching about understanding the required response time for any function driven by a switch (or any other signal for that matter). The correct method for debouncing must ...

Oooh, Oooh -- I just thought of one more reason -- I'm proud of my diagrams, but it's hard to draw a diagram of a piece of software (although I'm going to give it "the old college try" when we get to look at software solutions :-)

I wouldn't argue that debouncing in software is an excellent choice for high-volume production projects. Debouncing in hardware may be more appropriate for smaller projects and hobbyists. Having said this, there must be a reason why well-known devices like the MC14490 from On Semiconductor and the MAX6816 / 6817 / 6818 from Maxim Integrated ...

This entire series of articles has confused me. It reads to me more as a historical piece than as a practical guide for future designs. All (or nearly all) of the discrete hardware solutions cost more than software debounce on a low-cost microcontroller. I just priced a the MC 14490 hex ...

A related article "But, if we know that RTL is so bad, we also know somewhere, deep down, that we will need to do something different someday. But what? and When?" RTL goes back to "Verilog can be simulated, therefore we MUST us it for design entry" which is one ...

Hi Kev -- this may be old, but -- like so many things -- it wasn't something I'd heard about before, so I found this column to be pretty interesting.

BFLOAT16 is a human understanding of something that machines could work out for themselves more efficiently. Having worked on IEEE committees, I always find it predictable (and depressing) what folks will go for, but this one is rather old... https://www.youtube.com/watch?v=Kg7fu-CllnA

Hi Aubrey -- thanks for the reminder. The funny thing about all of this is that -- looking back --I've never learned anything that didn't eventually come in handy one day or another (the real trick is to use it before I forget it LOL). As we'll see in my ...

Max I thought I could point out to your readers who intend to use cross coupled NOR or NAND gates, that there are old CMOS parts, the CD4043 and CD4044, that include 4 such configurations allowing for 4 denounced switches per 16 pin IC. As I recall, they also have 3-state outputs allowing ...
