Abstract

PURPOSE:To easily confirm an executed instruction and its address, by constituting so that an execution time interval of the instructions can be set optionally. CONSTITUTION:A timing signal generated by a timing generating circuit 1 is inputted to a counting circuit 5. The circuit 5 counts the inputted timing signal and outputs its counting value. The outputted counting value is inputted to a coincidence circuit 6. As for its inputted signal, its coincidence with an instruction execution time interval which has been set by the counting value and a time setting circuit 7 is decided by the coincidence circuit 6. In this case, a reset signal and a coincidence signal are generated from the circuit 6 at every execution time interval. The reset signal is inputted to the circuit 6 and sets the counting value to ''0''. The coincidence signal is inputted to an address generating circuit 2, and this circuit 2 detects an address where an instruction is stored, in accordance with the coincidence signal, and reads out the instruction of its address. Subsequently, this executed instruction and the address are displayed on a displaying circuit 4.
