Information processing device

An information processing device comprising:

• a central processing unit including an execution unit coupled to an operand bus, and a control unit that controls operation of the execution unit, based on fetched instructions;
• and
• a debugging circuit that obtains trace data about how a program is executed in the central processing unit,
• wherein said control unit comprises a debugging function unit that collects instruction execution analysis data in the central processing unit,
• wherein said debugging circuit comprises:
• a trace acquisition circuit that imports instruction execution analysis data collected by the debugging function unit and data received from the operand bus via logic circuits which are used for separate purposes;
• and a trace output circuit for delivering outside the output of the trace acquisition circuit, and
• wherein said trace acquisition circuit comprises a sorting logic unit that sorts instruction execution analysis data collected by the debugging function unit and data received from the operand bus in order of processing done by the central processing unit.
