| Abstract: | The communication mechanism of the cores covering ARM core, DSP core and co-processors in general DaVinci heterogeneous multi-core processors is researched in this paper. The basic principle of inter-processor communication (IPC for short) is analyzed and then the interconnection of cores and the implementation of the IPC software are delivered for TMS320DM816x series DaVinci multi-core processors. Finally, a multi-channel HD video and audio system based on SysLink is developed to verify the IPC. The system is efficient and the IPC works well. |
