Gray Code Fundamentals – Part 4 Design How-To 6/29/2011 7 comments In this, the fourth installment of our mini-series, we take a look at generating sub-2^n Gray code count sequences comprising *consecutive values*
The interface roadblock Blog 6/28/2011 1 comment Interface – verb: Interact with (another system, person, organization, etc); noun: A point where two systems, subjects, organizations, etc., meet and interact.
Debug a microcontroller-to-FPGA interface from the FPGA side Design How-To 6/27/2011 2 comments Microcontrollers and FPGAs often work together in embedded systems. As more functions move into the FPGA, however, debugging the interface between the two devices becomes more difficult. The traditional debugging approach comes from the microcontroller side, which relies on a serial-port printout. This approach adds overhead and may cause timing problems.
Running around in ever-decreasing circles… Blog 6/23/2011 4 comments I tell you, there simply aren’t enough hours in the day to do all of the fun things that need to be done – so now I’m running around in ever-decreasing circles shouting “Don’t panic! Don’t Panic!”
I feel like a fool… Blog 6/17/2011 6 comments Here’s an old joke that usually gets a laugh. When someone says “I feel like a fool,” you should immediately reply, “So do I, but where are we going to find one at this time of the day?”
Gray Code Fundamentals – Part 3 Design How-To 6/17/2011 1 comment The term Gray code is typically used to refer to a binary sequence in which only a single bit changes value when transitioning between adjacent states.
The inventor of the bagpipes… Blog 6/15/2011 7 comments I had a rather interesting time yesterday evening, because I was invited to give a presentation on the use of social media to a group of inventors in Birmingham, Alabama.
A prediction ahead of its time? Blog 6/15/2011 3 comments Weeks before DAC this year, I made the bold prediction that this would be the year in which the FPGA-based prototyping woke up from its sleepy position.
ESC Silicon Valley Virtual Event Blog 6/15/2011 Post a comment Sad to relate, I didn’t manage to attend ESC Silicon Valley this year (it was on May 2–5), but I just heard that UBM Electronics is offering a virtual version of this event…
Who Woz that masked man? Blog 6/7/2011 3 comments It’s day #2 of DAC 2011 and I have to say that I’m having a wonderful time, not the least that yesterday I got to meet “The Woz” (Steve Wozniak – the co-founder of Apple Computers).

Blog Doing Math in FPGAs Tom Burke 12 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
