PURPOSE:To reduce hardware, by storing patterns, where contents of respective registers are driven to specific data busses, in the form of micro instructions in the control and storage device preliminarily. CONSTITUTION:For the purpose of sending contents of a certain register in register group 2 to display part, field data by which this register is selected, mode data by which the output of select circuit 5 is set as the output of ALU1, and field data by which data bus 38 is selected are stored preliminarily in the XS field, the AU field, and ES field respectively in respect to contents of address A2 of the control storage, and external address signal 30 gives A2, and the control is performed by control signal 37 so that select circuit 35 selects external address 30, and contents of address A2 of the control storage are stored in micro instruction 16 by giving trigger to timing generating circuit 36. |
