Abstract

PURPOSE: To secure an access to the data with no interruption of the process control and others by CPU by constituting the data memory with the memory part which is the control object viewed from the arithmetic control unit and the memory part for data transmission.
CONSTITUTION: The data produced through execution of one real control by CPU11 is stored directly in 1st data memory part 24. And a direct reference is possible for part 24 for the data necessary for execution of one real control by CPU11. For transmission of the data to external unit 4 from arithmetic unit 1, CPU11 gives the control information to data transfer control part 2. Based on this information, data transfer control part 22 transfers the data of part 24 to 2nd data memory part 21. With end of all data transfer, control part 23 performs transmission to the external unit. In the case of reception, the data transmitted from external unit 4 is stored in part 21. When all data are stored, the data are stored in part 24 based on the control information given from unit 4. And CPU11 refers to the data when necessary.
