Z80, Adieu

I’ve published several obituaries in EEJournal over the past few years, but this is my first such article for a microprocessor. After 48 years, Zilog has issued an end-of-life notice for the Z80 microprocessor, introduced in early 1976. I have a long history with the Z80 that stretches back all the way to that introduction year. I consider the Z80 to be the best 8-bit microprocessor ever designed, … Read More → "Z80, Adieu"

BYOD or BYOM to Synaptics’ AI-Native Edge Compute Party

I have two questions for you. First, what are the three key elements of any platform intended for the internet of things (IoT) and edge computing, both of which are where the internet “rubber” meets the real-world “road”? Second, what springs to your mind when you hear someone drop the company Synaptics into the conversation?

Let’s start with the second question first … Read More → "BYOD or BYOM to Synaptics’ AI-Native Edge Compute Party"

Designing Robust 5G Power Amplifiers for the Real World

Sponsored by Keysight

Simulating 5G power amplifier (PA) designs at the component and system levels with authentic modulation and high-fidelity behavioral models increases predictability, lowers risk, and shrinks schedules. Simulation software enables multi-technology layout and multi-domain analysis, evaluating the impacts of 5G PA design choices while delivering accurate results in a single virtual workspace. This application note delves into how authentic modulation enhances predictability and performance in 5G millimeter-wave systems.

There's no denying the 6502's success, brucehoult. It was the foundation for the Apple II, the Atari VCS, the Atari 400 and 800 personal computers, and many other truly successful products. Alas, the 6809 was a bit late to the party, but a fine machine that unfortunately had to compete with the 16-bitters ...

> I consider the Z80 to be the best 8-bit microprocessor ever designed A good one, certainly, but I think not the best. Even at the same time, the 6502 brilliantly made use of the fact that RAM of the time was as fast as logic (later also exploited by ARM) ...

Steve, Whenever I would look at a custom laid out (not automated) chip, I would infer whether they had issues (functional/timing) with the design (or where last minute changes found available 'free' space). The Z80 does look beautiful and logically arranged. Faggin did a wonderful job on the architecture ...

Really? That’s very depressing. That said, since I’m using a digital input/analog output architecture that mimics an advanced neuromorphic design, the CXL sounds like one possible solution to my memory problems - but then my doctor says that at my age, I just need to get more ...

For this “monkeyboy”, one “fud” (Phd) is usually just like another, but I must admit I certainly pay attention when you begin your article by quoting the august Dr. Emilio Lizardo! Bravo!

Hi Henrik -- your Vision AppKit is perfect -- just what I'm looking for -- I wrote about your Ensemble AI-MCU family a few weeks ago https://www.eejournal.com/article/new-mcus-provide-102-the-performance-at-10-2-the-power/ The combination of your chip and the miniature camera on that tiny Vision AppKit board ...

Hi Max, I think we here at Alif semiconductor can help you with this! I have an application that detects faces running on our tiny Vision AppKit, if you think that would work I'd be happy to send you one :-) Demo here - https://www.youtube.com/watch?v=...

A subset of this EDA acquisition game has been the development of FPGA tools. NeoCAD did the tools for AT&T's clones of Xilinx FPGAs, doing it so well it embarrassed Xilinx, so they acquired them. I still have the NeoCAD coffee cup.
