A General-Purpose High-Speed Logical Transform Image Processor

A new logical transform processor has been designed and its performance presented in this correspondence. The design incorporates the speed advantage of a locally parallel processor and yet has the capability of processing images of widely ranging dimension. Sixteen pixels are processed simultaneously using table lookup. Image size and neighborhood size are under program control of the host computer, a Perkin-Elmer 3220. This logical transform processor is capable of executing picture point operations in 50 ns.
