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"

The First Annual FPGA Awards – the Fibbies – celebrating 40 years of FPGAs

Welcome to the first ever (perhaps only) annual FPGA awards – the Fibbies. This year, 2025, marks the 40th year of the FPGA’s appearance in the electronics industry, when Xilinx introduced its first FPGA, the XC2064. The Fibbie awards celebrate actual and dubious achievements in the FPGA market during 2024. I got the idea for these awards after seeing a video for the … Read More → "The First Annual FPGA Awards – the Fibbies – celebrating 40 years of FPGAs"

OpenVPX and the Next Generation of Space Applications

My guest this week is Ralph Grundler from Aitech and we are chatting all about OpenVPX in space! Ralph and I discuss the increasing role that open standards are playing in space applications, how OpenVPX supports a systems-based approach for these types of designs, and how OpenVPX can also be used to support a variety of AI applications in space.

Autonomous Trucks are Trucking Our Way!

On the one hand, the overly enthusiastic predictions for fully autonomous automobiles have, thus far, fallen somewhat behind schedule (sad face). On the other hand, it now looks like we will see fully autonomous trucks barreling down our interstate highways circa 2027 (happy face).

The idea of autonomous automobiles has been around for longer than most people might think. For example, the concept of … Read More → "Autonomous Trucks are Trucking Our Way!"

Lattice Semiconductor’s Nexus 2 platform brings significant performance benefits to low-end FPGAs

While Altera and AMD continue to hammer away at the higher end of the FPGA spectrum – for example, see “AMD ups the ante in the RF-enabled FPGA poker game with the Versal RF family” – Lattice Semiconductor’s recent introduction of the Nexus 2 FPGA platform reconfirms the company’s commitment to smaller FPGA devices. Although the Nexus 2 platform employs … Read More → "Lattice Semiconductor’s Nexus 2 platform brings significant performance benefits to low-end FPGAs"

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 ...

Thanks for sharing, traneusee.

Thanks for the personal remembrance and the additional analysis, Pat Hays. I agree with your analysis. DSP is far from gone. It simply became symbiotic with FPGAs and CPUs.

Good article, Steve. On a personal note, I was privileged to work with Jim Boddie at Bell Labs for 7 years, as a DSP architect and colleague. He was a kind mentor, always thoughtful and straightforward, even when we argued. He is fondly remembered by many of us. DSPs are no ...

Do I have to use a different compiler for each different ISA? I think "yes" and that means that first I must find a RUST compiler for RISCV and each different ARM ISA.

Hi there -- thanks for your question. Before I answer, I should note that you refer to an inverting Schmitt trigger in your query -- I'm actually showing a non-inverting gate in my diagram (I was trying to keep things simple). But I take your point that in the real ...

Hi Mark -- just an aside, I gave a shout-out to Efinix at the 2022 FPGA Forum in Trondheim, Norway (see "Not Much Happened, or Did It?" https://www.eejournal.com/article/not-much-happened-or-did-it/)

It's hard to argue with that (so I won't :-)
Posted on Jan 29 at 8:59am by traneusee
Thanks for this article! In 1998, I used a 64-bit MIPS processor as a DSP, assembly-coded to run a few frequency component DFT as ADC samples arrived every 10 uS. Not calculate after all ADC samples are in memory, but calculate while ADC samples are arriving. As you state, FPGAs did not ...
