Abstract
PURPOSE:To realize the observation of state history in each cycle of a flip-flop (FF) selected optionally, by storing the state of an FF at a data processor part that is read out through scanning. CONSTITUTION:A machine cycle is sufficiently increased for a hardware debug, and an optional FF is selected out of all FFsF1-F9 within a data processor part 1 when a data processor is actuated. Then the state history in each cycle of the selected FF is stored in a state history device 5. Accordingly, the FFsF1-F9 can be all observed by selecting properly the FF.
