Abstract

PURPOSE: To improve the processing efficiency of a unit by storing parameter data from a memory to a read register to perform the print operation with one instruction.
CONSTITUTION: In the I/O control system where the print operation can be performed by one instruction with the print instruction of a parameter form, printer 3 has register 18 where a print digit position in the print line is defined by indication from CPU2. The instruction consisting of the OP field and the parameter address is read from memory 1 by CPU2 and is transferred to printer 3, and printer 3 reads out parameter data consisting of the print digit position, etc., from memory 1 according to the parameter address and stores it into register 18. As a result, the print operation can be performed by one istruction, and CPU2 can execute the processing of another program during the print operation, so that the processing efficiency can be improved.
