Do you speak GAL? [Peterzieba] does, and has pulled together a collection of documents and tools so that you can too. There’s a dividing line in electronic engineering education, between those who ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Ernie Smith is a former contributor to BizTech, an old-school blogger who specializes in side projects, and a tech history nut who researches vintage operating systems for fun. When it comes to major ...

Figure 1 Use a portion of a programmable-logic device or gate array to implement a Schmitt-trigger buffer (a) by adding either two (b) or four external resistors (c). Thanks to its internal hysteresis ...

The re-targeting of an application specific integrated circuit (ASIC) design in a field programmable gate array (FPGA) demonstrates the viability of using programmable logic in high-performance signal ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...

Back in the bad old days, if you needed a little bit of custom logic you would whip out a tiny chip known as a PAL. A Programmable Logic Array is just what it sounds like and is the forerunner of ...

Microchip has introduced a 32 logic elements programmable logic array into a microcontroller. Each logic element can simulate AND, OR, NAND or NOR gate, a buffer or inverting buffer, a D or JK ...
