Applications Of Programmable Logic Arrays To Video Rate Image Processing
Mitchell W. Millman · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1979
Programmable Logic Arrays (PLA's) are digital electronic devices capable of performing complex logic functions at very high rates - up to 20 million operations per second. They are available in many configurations including several types that can be field programmed using simple and inexpensive equipment. They are thus ideal devices for implementing several types of video rate image processing algorithms, particularly those algorithms that involve a high degree of adaptability or binary decision making. This paper describes the technology and operation of PLA's and details several representative image processing applications, including an adaptive differential signal compression algorithm, a gradient generator, and an edge continuity detector.
