Abstract: Aiming at the problems that the development of multiprocessor system is difficult and its efficiency is low, this paper proposes a remote debug scheme based on Joint Test Action Group(JTAG) for multiprocessor system. It realizes synchronous and asynchronous debug for multiprocessor, and offers abundant debug means. The multiprocessor debug system is implemented under Linux. Simulation test and practical application demonstrate that the scheme is efficient, and it can improve the efficiency of system development.
