摘要：A target CPU executes a user program in synchronism with an asynchronousoperation clock signal at higher speed than an operation clock signal of a debuggingobject system. A control unit portion outputs address bus information, data bus

information, and machine cycle information in operation. A POD portion generates variouscontrol signals of the debugging object system based on the machine cycle informationand then the address bus information, the data bus information, and the machine cycleinformation to the debugging object system in synchronism with an operation clocksignal of the debugging object system. Collection, output, or process of debugginginformation can thus be executed by use of difference in execution times of the userprogram between the debugging object system and the target CPU, without halting thedebugging object system.
