Can You Hear Me Now (With My 21st Century Studio-Quality MEMS Microphone)?

In England in 1969, what’s now known as British Telecom (BT) didn’t exist. In those days of yore, UK telecommunications (including telephones, exchanges, wiring, and equipment) were operated by the Post Office Telecommunications Department, which was part of the General Post Office (GPO).

The unabridged story of how the Post Office ended up in charge of telephones is wonderfully Victorian and slightly bonkers. To cut a … Read More → "Can You Hear Me Now (With My 21st Century Studio-Quality MEMS Microphone)?"

How to Stop Bad Actors Reverse Engineering Your ASICs/SoCs and FPGAs

Bad actors aren’t just reverse-engineering software; they’re tearing into the silicon itself. From peeling ASICs/SoCs like onions to extracting FPGA bitstreams, the hardware battlefield is heating up. Happily, some brain-bogglingly clever hardware obfuscation techniques can be deployed to flip the script. … Read More → "How to Stop Bad Actors Reverse Engineering Your ASICs/SoCs and FPGAs"

AI at the Edge? Meet Wi-Fi in Microwatts

I’ve just been introduced to a technology that has the potential to revolutionize battery- and ambient-powered AI-enabled sensors using Bluetooth or WiFi while consuming only 1/1000th the power of regular Bluetooth and WiFi implementations. Intrigued? Read on!

Before we plunge into the fray with gusto and abandon, indulge me, if you will. I read a lot of science fiction. One of the … Read More → "AI at the Edge? Meet Wi-Fi in Microwatts"

Ray Holt, inventor of the first microprocessor chip set, needs our help.

Ray Holt, inventor of the first microprocessor chip set, which was used as the digital flight computer in the US Navy’s F-14 Tomcat fighter jet, is ill and needs our help. I first wrote about Ray in 2022 (see “Ray Holt and the CADC – The World’s First Military Digital Flight Computer”). That article … Read More → "Ray Holt, inventor of the first microprocessor chip set, needs our help."

Upward and Onward! How MathWorks is Tackling Advanced Air Mobility Software System Design Challenges

This week’s podcast covers everything from the heights of the sky to the depths of the ocean. My guest is Paul Barnard from MathWorks, where we dive into one of my favorite subjects: Advanced Air Mobility (AAM). Paul and I discuss the major software development hurdles for AAM vehicles, the advantages that a modular software approach offers these designs, and how engineers are working to synchronize simulation models … Read More → "Upward and Onward!
