--INTEGRATED CIRCUIT INCLUDING CLOCK CONTROL CIRCUIT FOR DEBUGGING CIRCUIT AND SYSTEM-ON-CHIP INCLUDING THE SAME

摘要

The integrated circuit includes a processor core, a clock control circuit, and a debugging circuit. The processor core processes a plurality of instructions and data constituting the target software. The clock control circuit determines an electrical connection state between the processor core and an external debugger that performs a debugging operation on the target software, generates an output clock signal selectively activated based on the determination result and the input clock signal do. The debugging circuit provides information to the external debugger related to the debugging operation for the target software based on the output clock signal.
