VHDL arbiters
What is an arbiter? What is an arbiter? An arbiter is a very common block used on HW designs. I think I can find the best example of an arbiter at home. When my two kids were teenagers, I had only one car. On Friday and Saturday evenings, there was usually a conflict over who got to use the car. Usually, it was on me to decide (arbiter) who got the car. Not an easy task. (I still have only one car. It just happens that my kids are not teenagers anymore, and praise the Lord, they have their own cars). Continue reading...
SETI's FPGAs
FPGAs and GPUs: a Tour of SETI's Computer Hardware David MacMahon is a research astronomer with Berkeley SETI Research Center. Dave works on several projects at BSRC, including Breakthrough Listen, designing many of the computer systems we use to process data collected from our telescopes. If you've ever been curious what hardware is required to search for ET, check out this tour of Berkeley SETI behind the scenes.

As time goes by
The comics strip says it all... ... or maybe not. There are so many missing: Ethernet, Fast Ethernet, Gigabit Ethernet The diverse Windows versions... and Unix, and Linux Serial Rapid IO, Infiniband PDAs, disc-man, MP3-player, tablets, digital cameras ADSL, optic fiber, and so many others... BTW, I first thought about this comics strip while reading about IoT. Will it be a success or will it be forgotten? I remember that in its time, ATM was also thought to be "the next thing, for sure". Well, it didn't happen... What would your list have?
Analysis, elaboration and synthesis
Do you recognize that feeling when you think you knew something, until somebody asks you to explain it? Well, that was what happened to me when I tried to explain what "Analysis and Elaboration" is. I used it in FPGA tools many times, and I had a certain "knowledge" of what it was, but, what are those processes EXACTLY? And, while we are at it, we will also describe what Synthesis is. Let's see: Analysis Analysis is the process where the design files are checked for syntactic and semantic errors. The syntactic rules are dictated by the language. On VHDL, if you write IF but forget to include the THEN clause, that is a violation of the syntax , the set of rules of the VHDL language. Semantics are the meaning of the language. A sentence describing an addition is tagged as incorrect if the operands are of incompatible types and the VHDL compiler cannot resolve the meaning of that sentence. Elaboration VHDL designs are hierarchic by natur...
