Abstract :
The latest multiprocessor platforms are ideal for implementing multi-OS embedded applications. IPC (inter-processor communication) interface makes it possible for a multiprocessor system to easily support multiple subsystems parallel processing. In this paper, we propose a new type of OS-level communication interface designing based-on CMPS (complementary multiprocessor system) and present the primary principles and corresponding driver structure of HP I (host-port interface). Take a single-board embedded multimedia system which was integrated three embedded microprocessors (PXA255, TMS320DM642 and SM501) as hardware platform, detailed description of how implement tasks communication and A/V (audio/video) data transform via HPI between different OS(Linux and muC/OS-II) running on ARM and DSP separately.
