PROBLEM TO BE SOLVED: To provide a debug system and a debug circuit in which a tracing stack access and a normal data access are independently perforned so as to reduce the processing load of the debug system. SOLUTION: In the debug system equipped with a CPU as the object of debugging and a debug circuit, a CPU is configured to independently output the data access information of a CPU to be monitored by the debug circuit as information for stack access and information for data access excluding stack access, and the debug circuit is configured to independently generate and output the trace information of stack access from the information for stack access to be output by the CPU and the trace information of data access excluding the stack access from the information for data access excluding the stack access to be output from the CPU.
