The strange case of the Recalcitrant Roku 3 and the microSD card

August 14, 2024

I’ve been pretty hard on HP Inc. regarding my misadventures with that company’s inkjet printers, so I thought I’d go hard on another consumer product for a change while making some relevant design observations. While visiting my daughter in Silicon Valley recently, I noticed that her ancient Roku 3 media streaming box was behaving badly. It was responding very slowly. I got the Roku purple screen of death when exiting the YouTube app. I’d seen these symptoms before and suspected that the Roku needed more storage for the various channel apps so that it … Read More → "The strange case of the Recalcitrant Roku 3 and the microSD card"

Microchip’s PolarFire SoC Discovery Kit provides low-cost access to a powerful SoC FPGA development platform

by Steven Leibson

August 12, 2024

Nearly every new electronic system needs some sort of microprocessor or microcontroller. Modern microprocessor hardware is just too useful and too inexpensive not to include some amount of software programmability in any new product. In fact, my design recommendation for the past two decades, even immersed as I was in FPGAs, has been: If you can possibly use a processor to solve your problem, you absolutely should because it’s the simplest solution and the path of least resistance. Today’s processors are pretty darn fast, and they can sip tiny amounts of power if you put … Read More → "Microchip’s PolarFire SoC Discovery Kit provides low-cost access to a powerful SoC FPGA development platform"

AI + Robotics + Vacuum Tube (Valve) Amplifiers = AWESOME

by Max Maxfield

August 8, 2024

Way back in the mists of time we used to call the late-1970s, when I was a student at Sheffield Hallam University (or Sheffield Polytechnic as it was known back then), I was a member of the Joe Cool Road Show. In addition to providing the sounds and lights for on-site discos and visiting bands, we also provided support for local bands in various venues around the city.

One such band was the English synth-pop band called Read More → "AI + Robotics + Vacuum Tube (Valve) Amplifiers = AWESOME"

Nuvoton’s One-Arm M2L31 Microcontroller Uses ReRAM (Memristors) for On-Chip, Non-Volatile Storage

by Steven Leibson

August 7, 2024

Today’s world overflows with advanced multicore microcontrollers capable of running Linux and connecting over multi-Gigabit Ethernet. In such a world, Nuvoton’s 32bit NuMicro M2L31 microcontroller with its single core, 72MHz Arm Cortex-M23 processor and no Ethernet support stands out as a unique offering that harkens back to earlier days when microcontrollers were used in the design of embedded devices that were not connected to Ethernet or Wi-Fi networks. Even in today’s world, these sorts of applications still exist. Hence the need for these microcontrollers. Nuvoton has positioned these microcontrollers for embedded applications including … Read More → "Nuvoton’s One-Arm M2L31 Microcontroller Uses ReRAM (Memristors) for On-Chip, Non-Volatile Storage"

Weaving State-of-the-Art Chiplet and SoC Fabrics

by Max Maxfield

August 6, 2024

Are you familiar with a bird called the baya weaver (Ploceus philippinus)? These little beauties are to be found across the Indian subcontinent and Southeast Asia. Baya weavers are renowned for weaving unique and intricate hinging nests from different materials. These nests are robust and safe while also being extremely lightweight and efficient.

The reason I mention this here is that I was just chatting with Nandan Nayampally, who is the Chief Commercial Officer at Baya SystemsRead More → "Weaving State-of-the-Art Chiplet and SoC Fabrics"

Little Printers – HP Inc Strikes Again

by Steven Leibson

August 5, 2024

Back in March, I wrote about an over-the-air software update to my wife’s OfficeJet Pro 6978 printer that locked out some 3^rd-party ink cartridges that I had already purchased. (See “HP Inc tries to brick my wife’s printer. CEO approves and calls people like me “bad customers” on CNBC.”) In that situation, the 3^rd-party ink supplier, LxTek, saved the day by supplying a replacement ink cartridge with an updated … Read More → "Little Printers – HP Inc Strikes Again"

Want an Edge NPU for TinyML in AIoT Devices? Ceva Has You Covered

by Max Maxfield

August 1, 2024

I tell you; things are currently racing towards the edge where the internet “rubber” meets the real-world “road” in embedded space (where no one can hear you scream). Unfortunately, every time I say the word “edge,” I immediately think of the classic 1972 “Close to the Edge” album by Yes.

While the song and tune are rattling around my noggin, I visualize the image on the Read More → "Want an Edge NPU for TinyML in AIoT Devices? Ceva Has You Covered"

The Day the Earth Stood Still, 2024 edition: Crowdstrike anti-malware software update crashed the world

by Steven Leibson

July 29, 2024

Global cyber/software security giant Crowdstrike sent out a software update for its enterprise-class Falcon anti-malware software on Friday, July 19, and ended the world as we know it. The software update caused Windows to crash on an estimated 8.5 million PCs and servers worldwide and brought up blue screens of death (BSODs) on the PC displays of nearly all worldwide subscribers to Crowdstrike’s services including airlines, logistics companies such as FedEx and UPS, financial institutions, hospitals, pharmacies, 911 call centers and other emergency services, network television broadcast studios including Sky News in the UK and Canal+ in France, retailers, grocery … Read More → "The Day the Earth Stood Still, 2024 edition: Crowdstrike anti-malware software update crashed the world"

Customized Analog for the Connected World

by Max Maxfield

July 25, 2024

I’ve said it before, and I’ll doubtless say it again; I’m a simple man. As I’ve also said before, this isn’t a pause for you to agree with me enthusiastically because I haven’t completed my train of thought. What I was trying to say was that I’m a simple man who likes a simple story.

I hate it when, after talking to someone about some new product, service, or technology they are promoting, I’m left with my head spinning and no clue as to what … Read More → "Customized Analog for the Connected World"

Want to Run LLMs on the Edge?

by Max Maxfield

July 23, 2024

I’ve just heard something that left me flabbergasted. Seriously. I cannot recall the last time my flabber was quite this gasted. All I can say is that if you dare to read this column, your own flabber is in danger of joining mine, so this might be a good time for you to don clothing appropriate to the occasion.

Let’s start with the concept of generative AI (GenAI) models like ChatGPT and Stable Fusion. These are known as large language models (LLMs). LLMs usually run in the cloud; that is, on … Read More → "Want to Run LLMs on the Edge?"
