MIPS Rolls Out Its First RISC-V Processor Core – It’s a Big ‘Un

January 9, 2023

Even though the company had telegraphed its big move, MIPS’s adoption of the RISC-V ISA for its future processor cores hit me like a ton of bricks. MIPS is one of the heroes of the early RISC revolution, and the company has gone through a lot of ups and downs. Big ups. Big downs. Jim Turley discussed the MIPS announcement about joining the RISC-V gang last year. (See “Wait, What? MIPS Becomes RISC-V.”) Last … Read More → "MIPS Rolls Out Its First RISC-V Processor Core – It’s a Big ‘Un"

Developing the World’s First Commercially Available RF Device with an Open-Source Chip

by Max Maxfield

January 5, 2023

Good Grief! I can’t believe it’s 2023. I’m not ready. I haven’t got a speech prepared and I don’t have a thing to wear. I hope you had a wonderful holiday break with family and friends. For myself, I was originally hoping to take a 4-day weekend around Christmas Day followed by a repeat performance around New Year’s Eve.

Unfortunately, the former was not to be (too much work and not enough time—sad face). Happily, the latter did come to pass (happy face), but … Read More → "Developing the World’s First Commercially Available RF Device with an Open-Source Chip"

Does 2+2=4? Microchip announces PolarFire 2; You Do the Math

by Steven Leibson

January 4, 2023

Microchip previewed its PolarFire 2 mid-range SoC FPGA family at the RISC-V Summit last month in two presentations including a keynote given by Bruce Weyer, the company’s Corporate VP for FPGAs. Although the company provided very few product details, it dropped many hints. So many hints, in fact, that I can give you the information I’ve collected based on these hints, tell you what I think, and let you come to your own conclusions. I’ll give you the “2”s and let you check my math, but then you’ll need to add the “2”s … Read More → "Does 2+2=4? Microchip announces PolarFire 2; You Do the Math"

A History of Early Microcontrollers, Part 9: The General Instruments PIC1650

by Steven Leibson

January 2, 2023

I almost did not write this chapter in the ongoing saga of early microcontroller history. That’s not because the PIC1650 microcontroller isn’t important, just that it was not very important in its first incarnation. General Instrument Microelectronics (GI) envisioned the PIC1650 microcontroller as a peripheral chip for its 16-bit CP1600 microprocessor. In fact, “PIC” originally stood for “peripheral interface chip,” but the company eventually changed that meaning to “programmable intelligent computer.” Neither the CP1600 microprocessor nor the PIC1650 microcontroller made much impact on the industry during the 1970s. However, GI went through a couple … Read More → "A History of Early Microcontrollers, Part 9: The General Instruments PIC1650"

Introducing SafeConnect Connectivity and Glitch Sign-Off from Real Intent

by Max Maxfield

December 29, 2022

Sometimes I cast my mind back longingly to my early days as a design engineer when things were so much simpler than they are now. When I was working on my first ASIC, there was no thought of using functional blocks of intellectual property (IP) from third-party vendors because there were no such things as functional blocks of IP from third-party vendors.

Similarly, we didn’t talk in terms of things like “connectivity fabric” because all we had was wires that connected our logic gates and registers together.

Yet Another 100 Captivating Columns and Counting!

by Max Maxfield

December 27, 2022

I sometimes wonder how many words I’ve written professionally in my lifetime. At least two of my books (search for “Clive Maxfield” on Amazon) have exceeded 850 pages, but I have no idea how this equates to words, and I have no intention of spending any of the precious seconds I still have on this plane of existence counting them. … Read More →

Are Agricultural Drones Poised to be the Next Big Thing?

by Max Maxfield

December 22, 2022

The latest research indicates that Homo sapiens—the species to which you, your humble narrator, and all other living human beings on this planet belong (even the French)—first made its appearance sometime around 300,000 years ago (possibly on a Wednesday morning, but don’t hold me to that).

It took most of the past 300,000 years for our population to reach 1 billion people, a milestone the United Nations (UN) organization estimates occurred in 1804. It took only 123 years after that before the population doubled to 2 billion souls in 1927, and just 33 more years … Read More → "Are Agricultural Drones Poised to be the Next Big Thing?"

Lattice Strides Into the Mid-Range FPGA Arena With Avant

by Steven Leibson

December 21, 2022

Lattice Semiconductor is moving upscale with its new mid-range Avant FPGA platform. After spending the last several years taking low-end market share from its bigger FPGA competitors, essentially while they weren’t looking, Lattice has decided that a similar opportunity awaits in mid-range programmable-logic parts. I think the jury is out there. … Read More →

A History of Early Microcontrollers, Part 8: The Intel 8051

by Steven Leibson

December 19, 2022

Intel introduced the successor to its 8048 microcontroller, the 8051, in 1980. It’s become the immortal microcontroller, and it was all because an applications engineer forgot to bring his wallet to work one day and asked his boss at Intel to buy lunch.

Intel announced the 8048 microcontroller in 1976. The design’s largest weakness, limited memory addressability, reared its head within the first year. In one sense, that’s a great problem to have because it suggests that customers wanted even more of a good thing. Intel sold $7 million worth of 8048 and 8748 microcontrollers … Read More → "A History of Early Microcontrollers, Part 8: The Intel 8051"

Arduino 0s and 1s, LOW and HIGH, False and True, and Other Stuff

by Max Maxfield

December 15, 2022

It’s common to hear engineers and computer boffins say that digital computers are based on 0s and 1s, but what does this actually mean? On the one hand, this is relatively simple; I mean, 0 and 1, how hard can it be? On the other hand, there are so many layers to this metaphorical onion that, much like a corporeal onion, it can make your eyes water. … Read More →
