ABSTRACT:
The specification discloses a system and method for processing digital representations of images by routing the representations sequentially through a plurality of function units. Each function unit includes a delay for delaying one of two inputs and a logic unit for performing logical operations on the delayed and undelayed signals to produce two outputs. The logic unit performs any one of a plurality of logic functions as dynamically selected during processing. Specific functions of particular interest include (1) ORing the delayed signal and the original digital signal and (2) ANDing the delayed signal and the original digital signal. The delay includes a first shift register through which the serial signal is shifted, a storage device for storing signal segments read from the first shift register, and a second shift register into which the segments are returned from storage to be re-serialized to produce the delayed signal.
