Describes the use of one erasable PLD device, the EP1800, in an application where it provided a most elegant solution to an engineering problem. The Altera EP1800 is a 2100 gate equivalent part and is the largest PAL architecture device made by that company. Here it is used as a microprocessor peripheral in the navigation system of an underwater vehicle. It was a requirement of the design that 24 acoustics channels in the range 7-17 kHz are processed simultaneously and as L-C filters have served well in the past, 24 of these were provided on a single printed circuit board along with an EPLD to interface them to the microcontroller
