Abstract
A microprocessor has a plurality of debug modules, multiple sets of processor cores provided corresponding to the debug modules so that each set of the processor cores are debugged by the corresponding debug module, and a plurality of debug ring units provided corresponding to the debug modules, each debug ring unit generating a debug ring signal for instructing the corresponding processor cores to transit to a debug mode. The debug ring units are connected to generate a ring and sequentially transmit the debug ring signal, and when receiving the debug ring signal, each debug ring unit outputs, to the corresponding debug module, a debug transition signal for instructing the corresponding processor cores to transit to the debug mode.
