Chimera GPNPU Blends CPU, DSP, and NPU into New Category of Hybrid Processor

According to Greek mythology, the Chimera (a.k.a. Chimaera) was a monstrous fire-breathing hybrid creature that was composed of different animal parts. These days, the term "chimera" has come to describe (a) any mythical or fictional creature with parts taken from various animals, (b) anything composed of very disparate parts, or (c) anything perceived as wildly imaginative, implausible, or dazzling. … Read More → "Chimera GPNPU Blends CPU, DSP, and NPU into New Category of Hybrid Processor"

Virtualized IoT Devices in the Cloud Run Faster Than Their Real-World Counterparts!

I’m not a giddy software guru. I’m a hard-bitten hardware guy. I remember those days of yesteryear when I hadn’t even heard about esoteric things like virtualization, containerization, disaggregation, and other “-ations,” the discussion of which does my poor old noggin no favors whatsoever.

Now, by comparison, I know enough to nod knowingly and grunt appreciatively when … Read More → "Virtualized IoT Devices in the Cloud Run Faster Than Their Real-World Counterparts!"

A History of Early Microcontrollers, Part 3: The Rockwell Microelectronics PPS-4/1

Now that we’re well into the 21st century, most people rarely think of Rockwell Microelectronics in connection with microprocessors and microcontrollers. The parent company, North American Rockwell (renamed Rockwell International in 1973), was a major military/aerospace contractor. Rockwell built the Apollo spacecraft, the B1 Lancer bomber, and the US Space Shuttle. Rockwell’s Rocketdyne engines were used … Read More → "A History of Early Microcontrollers, Part 3: The Rockwell Microelectronics PPS-4/1"

Fish Fry 500: The Best of Photonics (Now on Youtube!)

I also … Read More → "Fish Fry 500: The Best of Photonics (Now on Youtube!)"

A History of Early Microcontrollers, Part 2: The Texas instruments TMS1000

As with many first-of-a-kind devices, the Texas Instruments (TI) TMS0100 calculator chip family was a narrowly defined microcontroller, mostly good for making calculators. However, the first chip in the TMS0100 family, originally called the TM1802NC and later renamed the TMS0102, incorporated everything a microcontroller requires to be a microcontroller: a CPU, RAM, ROM, and I/O. Granted, it was a specialized microcontroller. Its I/O … Read More → "A History of Early Microcontrollers, Part 2: The Texas instruments TMS1000"

Current Sense Resistor - WFC & WFCP Series

Sponsored by Mouser Electronics and Vishay

If you are working on a telecom, consumer or industrial design, current sense resistors can give you a great way to detect and convert current to voltage. In this episode of Chalk Talk, Amelia Dalton chats with Clinton Stiffler from Vishay about the what, where and how of Vishay’s WFC and WFCP current sense resistors. They investigate how these current sense resistors are constructed, how the flip-chip design of these current sense resistors reduces TCR compared to other chip resistors, and how you can get started using a Vishay current sense resistor in your next design.

How SHP in plastic packaging addresses 3 key space application design challenges

Sponsored by Texas Instruments

TI’s SHP space-qualification level provides higher thermal efficiency, a smaller footprint and increased bandwidth compared to traditional ceramic packaging. The common package and pinout between the industrial- and space-grade versions enable you to get the newest technologies into your space hardware designs as soon as the commercial-grade device is sampling, because all prototyping work on the commercial product translates directly to a drop-in space-qualified SHP product.

Normally, I'd say it was silly for the USSR chipmaker to have copied the Rockwell logo on the chip, Wally. But after reading Federico Faggin's autobiography "Silicon" and learning about the traps he put in the masks to catch unwary copiers of the Z80, I don't think it's silly any ...

Hi Steve -- this is awesome -- I was aware that the first commercial microprocessor (the Intel 4004) came about as part of a calculator project, but I had no idea that the first commercial microcontroller started out the same way -- I can't wait to read Part 2!

The light bulb does have a short-term memory, as the filament's resistance depends upon the average RMS sinewave power over a fraction of a second, rather than upon the instantaneous power. This averaging is why the light bulb can regulate the oscillation amplitude without distorting the sinewave.
