A real-time debugger implementation maintains and manages multiple debug contexts allowing developers to interact with real-time applications without "breaking" the system in which the debug application is executing. The debugger allows multiple debug contexts to exist and allows break points in real-time and non-real-time code portions of one or more applications executing on a debug enabled core of a processor. A debug monitor function may be implemented as a hardware logic module on the same integrated circuit as the processor. Higher priority interrupt service requests may be serviced while otherwise maintaining a context for the debug session (e.g., stopped at a developer defined breakpoint). Accordingly, the application developer executing the debugger may not have to be concerned with processing occurring on the processor that may be unrelated to the current debug session.
