ABSTRACT:
A debug system according to the invention is used in a multiprocessor system for executing a plurality of programs while taking check points. This debug system comprises detection section for detecting an error in any of the programs, restart section for shifting the programs to a debug mode and restarting the programs from a check point which has been taken immediately before occurrence of the error, when the detection section has detected the error, and section for executing the programs in the debug mode such that a history of the execution of the restarted programs is reproduced. The programs are again restarted from the check point when a next check point has been reached without reproduction of the error.
