Replacing discrete 7400 logic devices with CPLDs
Whether you are working on a retro computing device, or experimenting with digital logic, you’ll find that in most instances CPLDs can perform the same operations as a cluster of 7400 series discrete logic chips. Discrete logic devices, long considered the workhorses of the semiconductor industry, held a unit cost advantage over programmable logic devices […]
Mini robot design using CoolRunner-II CPLD
It’s National Robotics Week, and what would National Robotics Week be without a CPLD based mini robot design? Here’s a mini robot design project outline (PDF!) found in the World Academy of Science, Engineering and Technology journal. While it’s not a “how to” style article (no schematic/code provided), it describes the advantages of using CPLDs […]

Architecture of FPGAs and CPLDs: a tutorial
Stephen Brown and Jonathan Rose of the Department of Electrical and Computer Engineering, University of Toronto, authored this paper providing a tutorial survey of architectures of commercially available high-capacity field-programmable devices (FPDs). They first define the relevant terminology in the field and then describe the evolution of FPDs. The three main categories of FPDs are […]
