PURPOSE:To execute debugging of a software even when a target machine is not completed yet, by constituting the titled emulator so that a signal of an I/O port can be inputted manually. CONSTITUTION:A host I/F 2 in which a pod part and a host computer are connected to a target I/F 3 in which the pod part and a target machine are connected, and an input means 4 is connected to a one-chip microcomputer 1 connected to the I/F 2 and the I/F 3. Also, as for an input port of the microcomputer 1, an output from the means 4 is executed preferentially irrespective of the I/F 3, and as for an output port of the microcomputer 1, the I/O executes preferentially the output from the means 4 irrespective of High/Low of a bus 7. |
