Predictions for Multi-Die System Designs in 2025

There’s a famous saying along the lines of, “Predicting things is difficult, especially about the future.” This quote has been attributed to many people, including Mark Twain, Niels Bohr, and Yogi Berra. In Yogi’s case, however, it’s usually phrased as, “It’s tough to make predictions, especially about the future.”

I know that when I staggered into the current millennium, … Read More → "Predictions for Multi-Die System Designs in 2025"

“H” is for Heathkits and Hams: Part 1 – Early Days through the 1950s

Late last year, I published a 6-part article series that recounted the history of the Heath Company and its world-famous Heathkits. The series was based on an interview with Chas Gilmore, who joined the Heath Company in 1966 as a design engineer and worked at the Heath Company for more than two decades, eventually becoming VP of product development, marketing, and sales and finally EVP and General Manager. … Read More → "“H” is for Heathkits and Hams: Part 1 – Early Days through the 1950s"

In Memoriam: James Boddie, DSP Pioneer

Starting with the development of the world’s first single-chip DSP, the Bell Labs DSP1, Jim Boddie devoted his long career to expanding the world of digital signal processing. His early work in developing signal-processing algorithms on minicomputers with attached array processors led him to cutting-edge signal-processing research at Bell Labs. That work resulted in the development of the DSP1, which AT&T successfully deployed in … Read More → "In Memoriam: James Boddie, DSP Pioneer"

Hi Steven, Very nice article. I read your previous article also. One possible deployment of disaggregated memory in a data center rack can be follows - - PCIe Backplane based rack - CPU blades in the rack will have only nominal DRAM - Rack will also have Memory expander blade(...

Thanks Chas. I'm hoping you're posting these articles to those Facebook groups. It'd be a shame for them to miss out. --Steve

As I am sure many of you know, there are a number of Heathkit related groups on Facebook. One nice feature of these groups is there are a number of former Heath employees who follow those groups and, from time-to-time they’ll respond to posts providing unique responses that come ...

Thanks. That is almost the same as having a different compiler. Also I am guessing support for plain old C? C# has recently added conditional assignments which eliminates a lot of if/else/branch statements. So now we have a programming language source syntax that closely resembles the logic expressions ...

Hi RedBarnDesigner -- I can't wait to hear what you think about "The Story of Earth" by Hazen. It's one of my favorites. A couple of others I always recommend are "The Disappearing Spoon" by Sam Keen, "Wetware: A Computer in Every Living Cell" by Dennis Bray, and "Life's Ratchet: ...

Rust is relatively tightly coupled with LLVM which is generally pretty straight forward for supported targets. Embedded use and support tends to vary a lot outside that. https://rust-embedded.org/ Is your best starting point. That said you should get some pretty reasonable code reuse.

Hi Karl and Red (and Red and Karl -- no favorites here) -- I'm going to ask the folks from Ferrous Systems to chime in here -- in the meantime, what did you think to my wafflings about rust in the context of Earth's evolution (as opposed to the evolution ...

C# is opensource, has conditional assignments that are more user friendly than using C if/else for conditions. Since I am a logic designer,my preference is to design rather than us an embedded processor with all the levels of cache, DDR, etc. At the lowest level, the C language ...

Time for a bucket of cold water maybe? I thought Rust was a good language when I first looked at it some years ago and it certainly has gained some traction, but.... MODCARGO_CRATES anyones!!! Take a look at the infrastructure overheads involved! It certainly tidies up a lot of ...
