PURPOSE:To improve a processing speed by switching each of three data store areas exclusively and circularly to each other to states for a data reception, for a data transmission, and for write/read-out of a data operation, and executing in parallel data reception, data transmission and data operation processings. CONSTITUTION:Each data store area 1-3 for a data reception for receiving a data from the outside through a data receiving terminal 6, a data transmission for transmitting the data to the outside through a data transmitting terminal 7, and a data operation processing for supplying the data to an operation executing unit 4 and receiving a result of operation are provided so that they can be switched exclusively and circularly to each other, to states for a data reception, for a data transmission, and for a data operation processing. In this state, by controlling the switching of each part of the data reception, the data transmission and the data operation processing of each data store area 1-3, a data transfer processing between data processors and a data operation processing by each data processor can be executed in parallel. I such a way, the processing speed is improved. |
