Abstract

The invention belongs to the technical field of digital signal processors, and particularly relates to a non-intrusive real-time monitoring debugger for a DSP (digital signal processor). The real-time monitoring debugger comprises a bus monitoring module and a tracking buffer module, and the bus monitoring module and the tracking buffer module jointly complete debugging and obtain real-time operation information. The bus monitoring module is used for monitoring the memory access operation of the DSP, and meanwhile, the tracking buffer module is used for recording execution tracks of a program before and after an event, so that comprehensive and accurate debugging information is provided for a system, and problems occurring in the running process of the DSP can be quickly positioned and solved, and the debugging efficiency is improved; in addition, by arranging a special register, high configurability is achieved, so that monitoring and recording strategies can be flexibly adjusted according to different debugging requirements, and the debugging process is more targeted and efficient.
