Abstract
An instruction-based parallel median filtering processor and method sorts in parallel each combination of pairs of inputs into greater and lesser values; determines from that sorting the minimum, maximum and median filter values of the inputs; processes one of those values and provides the processed value as an input; and applies an instruction for providing one of the values to the processing step, and at least one other instruction for enabling indication of at least one of the maximum, minimum, median filter values.
