Abstract

PURPOSE: To facilitate an easy confirmation for the state of operation, by displaying the state of operation via a display switching means with the general equation corresponding to a calculation equation or either one of the numerical data such as the register data, the operation result data and the like.
CONSTITUTION: The microprogram which controls the entire part of a computer is stored in the ROM1, and the microinstructions AD2, INS and NA are delivered in parallel from the area corresponding to the address of the ROM address part 2. The instruction INS is decoded by the instruction decoder 4, and various types of R/W signals are applied to the RAM3. Furthermore the next address is designated by the instruction NA to be supplied to the part 2. Then an operation is carried out through the arithmetic circuit 7 and based on the indication of the key input part 8, and the decision result J is applied to the part 2 from the deciding circuit 6. Then the state of operation displayed at the display part 9 is displayed through switching the general equation corresponding to a calculation equation and either one of the register data, the operation result data by the display switching means 12. In such way, the confirmation can be facilitated for the state of operation.
