ABSTRACT:
A data processor of the invention includes plural memories, plural arithmetic units, a data transfer unit and a network. The data transfer unit transfers various data to predetermined memories, and switches the connections between the memories and the arithmetic units by using the network. The control unit adds a processability judgement signal to a data read from a predetermined memory in reading the data, so as to make a pair of the data and the processability judgement signal. Each of the arithmetic units receives the data and the processability judgement signal, conducts predetermined processing on the received data, delays the received processability judgement signal by the number of cycles equal to its own processing cycle, and outputs resultant data obtained through the processing and the delayed processability judgement signal. Accordingly, in storing ultimate resultant data in a predetermined storage unit, the storage unit stores the ultimate resultant data as effective data on the basis of the processability judgement signal added to the resultant data. The data processor attains wide application and can be applied to various types of multimedia applications by switching the connections between the memories and the arithmetic units by using the network.
