ABSTRACT:
Debugging a multiprocessor system utilizing at least two debuggers is disclosed. A user command is issued through a first debugger to a first processor in the multiprocessor system. The user command can be converted to a debugger RPC command by a first proxy module associated with the first debugger. The user command can be intercepted by a scheduler. A second processor in the multiprocessor system is then informed, for example by the scheduler, of the issuance of the user command. The user command is executed by both the first and second processors and both the first and second debuggers can then be informed by means of processor RPC commands of the execution of the user command. The processor RPC commands can be converted to callback commands by respective first and second proxy modules associated with the first and second processors when being sent to the first and second debuggers.
