<p>A motion compensated predictive coding/decoding system of a picture signal in which one frame is constituted by N x M pixels. The picture signal is divided into a plurality of block data each having BH x BV pixels. The plurality of the block data are coded/decoded with motion compensated prediction by processors (P), the number of which provided in horizontal and vertical directions being K and L respectively. The plurality of the block data to be coded/decoded are supplied to the processors. On the other hand, data of a former frame stored in KxaxLxb memories (M), each covering N/K/a x M/L/b pixels. By a bus adapter (BA), connection between the processors and memories is switched in accordance with a block position in the frame to be processed so that the processors can access the memories that store the data required for the motion compensated prediction. Any of the memories is not connected simultaneously to a plurality of the processors. <IMAGE></p> |
