An application specific signal processor architecture supporting nonlinear operations has been designed. The most essential block of the processor core is a programmable order statistic filter, for which the most feasible structure consists of a switch array and a programmable positive Boolean function. The core architecture supports rank order filters, linear and hybrid filtering.
