Hey! Hey! What Did You Say?

Speech recognition is becoming more and more critical in IoT designs these days. In this week’s episode of Fish Fry, Gerard Andrews (Cadence Design Systems) and I are talking about the trends in voice control user interfaces, the advantages of locally-enabled speech recognition, and the differences between neural network processing for audio and imaging applications. Also this week, we celebrate Valentine’s Day with a special selection of … Read More → "Hey! Hey! What Did You Say?"

Who Will Win AI at the Edge?

We’ve written a lot about AI in the cloud, and we’ve discussed data center solutions such as GPUs, high-end FPGAs, and dedicated AI chips such as Intel’s Nervana. For many applications, training and inferencing CNNs and other AI-based systems in cloud data centers is the only way to get the compute power required to crunch the vast data sets and complex models. But, … Read More → "Who Will Win AI at the Edge?"

Pimping My Variac Autotransformer (Actually, it’s a Philmore)

It seemed like such a good idea at the time.

I’ve wanted an autotransformer for electronic troubleshooting work for a while. Autotransformers are variable transformers that let you bring the AC voltage up slowly on a piece of gear under test. I owned a Radio Shack/Micronta variable transformer for decades, but it didn’t survive my move to … Read More → "Pimping My Variac Autotransformer (Actually, it’s a Philmore)"

ARM Floats Helium for Cortex-M

“I’m sorry, but neon just doesn’t look good on anybody!” — Tiffani Thiessen

First there was Neon, now there’s Helium. ARM has pulled the wraps off a package of DSP and machine-learning extensions for its low-end Cortex-M processors, sort of like Neon but not. Whereas Neon added DSP features to the Cortex-A family, Helium adds similar, but different, features to … Read More → "ARM Floats Helium for Cortex-M"

In Memoriam: Dr. Bernard Peuto, Architect of Zilog’s Z8000 and Z8

My friend Bernard Peuto passed away this month. We first met two decades ago when I moved to California to join the Microprocessor Report. Bernard was … Read More → "In Memoriam: Dr. Bernard Peuto, Architect of Zilog’s Z8000 and Z8"

Small, Selective Gas Sensors

One of the annual features at the MEMS and Sensors Executive Congress is the Technology Showcase, where 5 start-ups (or start-upoids) give quick presentations about their new ideas in exchange for visibility and prizes. One of this year’s contenders was Abhishek Motayed of n5 Sensors, who presented what looked like a promising new gas sensor platform. The nature of the event is such that you can’t go into … Read More → "Small, Selective Gas Sensors"

Complex processors are hard to take advantage of without good programming models, many excellent efforts have died due to lack of usability, I suspect this will be one of those. There's also no indication that ARM know anything more about this market than anyone else, and it seems likely the ...

I joined Onyx Systems founded by Bob Marsh, under Craig Forney (lead software guy) in Jan 1980, when the company was working out of a cage on the IMI shipping and receiving dock ... both funded by Carl Berg . When the contractor for the UNIX port defaulted in March(failed to deliver) ...

It's interesting that the headline features of lane predication and using the vectorized loop to deal with odd-length loop tails are shared with SVE and the RISC-V Vector extension, making MVE more similar to those than it is to NEON. It's also interesting that the fixed 128 byte vector register file ...

PS I'm thinking beyond just my own personal needs. Lots of those folks outside the range aren't tech savvy and don't have the money to spend on expanding the network that the MNO won't invest in. i think we tech folks think that everyone knows what we know. Solutions that ...

As far as I know, a cell booster works only if there's access (albeit weak) to a tower. I suppose I could shout louder with a booster, but there's zero signal to receive, so there's nothing to boost.

Does Helium fill a hole in your product plans, or is it pointless fluff?
Posted on Feb 19 at 10:00pm by KKrewell
Thanks for that history, Steve! I didn't spend as much time with Bernard at MPR, but he did help advise on our business, but rarely on technical areas. In 1979, I was working at Hazeltine, which, among other things, made computer terminals. Those terminals (and a word processor in development) used ...
