Architecture of FPGAs and CPLDs: A Tutorial [pdf]

I had bought an inexpensive FPGA board to play around with programmable logic and then later learned about CPLDs (from a bigmessowires project report at http://www.bigmessowires.com/68-katy/), which seemed a better, cheaper fit for what I want to do.

I wanted to know more about the background and history of these programmable logic technologies and this tutorial was fantastic, so I posted it here.

Hackaday also has some great articles and tutorials on this topic: http://hackaday.com/2008/12/11/how-to-programmable-logic-dev..., http://hackaday.com/2014/04/06/cpld-tutorial-learn-programma...
