PIPADS, the Parallel Image Processing and Display System, is an architecture targeted at supporting real-time image processing tasks at low cost. The machine uses an inexpensive semicustom SIMD array which, through supporting scan-line-based algorithms, can produce mega-pixel perspective views of terrains in real-time. This paper presents the constraints placed on the SIMD array, and details the how the architecture and implementation minimize hardware, time and volumetric costs.
