Picture processing system of plural processors

Abstract

Abstract PURPOSE:To improve the operating rate of a processor and to shorten the processing time, by sharing uniformly the number of coordinate to be calculated at the generation of a graph to each slave processor. CONSTITUTION:A multiplexer MPX switches a system control address SCA to a refresh memory RM and an access address of the slave processor SP. Processor modules PM1-PMn are programmed internally so that a continuous screen element is shared in order as to each raster on the screen and the operating processing such as the generation of a graph is executed at each of n-set of the screen elements. A master processor MP8 decodes a picture processing instruction inputted from an external circuit and gives a processing instruction in parallel to all the SPs. A system control circuit 13 generates a timing control signal such as supply of addresses to the RM under the control of the MP8.
