Abstract
PURPOSE:To efficiently execute debugging, by transferring the history quantity of a specific signal stored in a first trace storage means to a second trace storage means when it arrives at a prescribed quantity. CONSTITUTION:The titled device is equipped with the first trace storage means 4, the second trace storage means 6, a transfer control means 5, and a restarting means 3. On a mode register 4, '1' is set from the outside when a tracer mode is designated, and a hold circuit 5 stops the data processing of an arithmetic processing unit 1 when the value of a tracer counter 3 arrives at the prescribed value, and transfers the content of a tracer 2 to a main memory 6. When all of the contents are transferred to the main memory 6, the tracer counter 3 is reset, and the arithmetic processing unit 1 starts the processing of data again, and transfers a signal to the tracer 2. In such a way, it is possible to obtain the data effective for the debugging as much as possible.
