Abstract

PURPOSE:To ensure an effective debug of a program for a data processor formed into an LSI, by executing the trace program in response to the single interruption given with every execution of a microinstruction. CONSTITUTION:When the interruption signal 83 is turned on while the microinstruction 812 next to the main program 81 is being executed in the trace mode, both the interruption responding to the interruption signal plus the single interruption are ready to be given simultaneously when the instruction 812 is over. However, the single interruption has a low priority and is thus branched to the interruption process program 82 in response to the signal 83. When the single interruption process mask is opened even under a process of an interruption, the single interruption is given again when the swapping action 861 completes to be branched to the single interruption process program 84. In such way, a tracing is given also to the normal interruption process program 82 by the single interruption process program and with every execution of a microprogram.
