ABSTRACT:
A distributed video frame store and real time processing system which includes a frame store subdivided into a number of sectors each with an associated arithmetic unit capable of parallel operation for processing data from all the sectors simultaneously. Each arithmetic unit which comprises a subtractor, multiplier and adder may be shared as a common input and output processor during write and store read cycles respectively for that sector. During a write cycle, the incoming data together is processed with previously stored data and then written into the store sector, the coefficient for the multiplier being selected in dependence on any difference measured in the subtractor. During a read cycle and stored information can be passed via the arithmetic unit to the output. During the read cycle, data from two locations within that store sector is processed, and in dependence on any movement previously detected, these locations can be from the same or alternate fields.
