Abstract
A system for real-time digital processing of a video signal using a large number of one-bit serial processor elements each of which operates on one pixel of a horizontal scan. The video signal is converted to digital by an A-to-D converter, and stored in a set of input registers, one register for each processor element. All of these input registers are loaded during a horizontal scan, as the input registers are addressed in sequence by a commutator. Each processor element includes a one-bit binary adder, a set of one-bit registers, and two one-bit wide data memories of a size to store data from several scans. The processor elements are all controlled in common by a sequencer, a state machine or a processor. The processed video data is transferred to an output register for each processor element, from which it is converted to a video signal by a D-to-A converter. A frame memory may be used to save a processed frame for use in convolving the next frame; the input of the frame memory is taken at the output registers, and the frame memory output is applied to the input registers.
