PROBLEM TO BE SOLVED: To realize real time trace on mass production chips with a small number of terminals, and to attain trace even when an absolute branch instruction is executed continuously or with short intervals. SOLUTION: This system 20 is a debug system for outputting status information indicating the execution state of a CPU 12 and the trace information of a target system to device an absolute branch destination address and output them. In this case, this system includes a trace information generating part 27 which generates trace information by specifying a part other than one part of the absolute branch destination addresses based on at least one of information related with an address area in which a program to be executed by the target system is present and the status information received from the target system at the time of receiving one part of the absolute branch destination addresses from the target system. |
