The guys over at hackshed have been busy. [Carl] is making programmable logic design easy with an 8 part CPLD tutorial. (March 2018: Link dead. Try the Wayback Machine.) Programmable logic devices are ...

Complex programmable logic devices (CPLDs) contain the building blocks for hundreds of 7400-serries logic ICs. Complete circuits can be designed on a PC and then uploaded to a CPLD for instant ...

CPLD (Complex Programable logic devices) are as their name indicate programmable devices that can be used to implement logic functions. This is useful to expand an arduino board with more capabilites ...

Abstract: This tutorial surveys commercially available, high-capacity field-programmable devices. The authors describe the three main categories of FPDs: simple and complex programmable logic devices, ...
