Multi-core processor debugging system

The invention relates to a multi-core processor debugging system which comprises a master controller, microprocessor IPs (Internet Protocols) and a debugging state controller.Debugging control units in the microprocessor IPs and a debugging control unit in the master controller are connected with the debugging state controller for feeding debugging requests of the microprocessor IPs and the master controller back to the debugging state controller, and transmitting debugging response signals sent by the debugging state controller to the microprocessor IPs and the master controller. In the debugging system, the number of the integrated microprocessor IPs is unrestricted, debugging structures in the microprocessor IPs are not required to be changed, and the debugging system is easy to realize. The debugging state controller receives debugging request signals of the master controller and the microprocessor IPs, and synchronously control debugging of the master controller and the microprocessor IPs, so that cores
