Abstract

This paper focuses on the realization of a complete embedded system using the dual-core processor OMAP5910. Detailed description of how to compose the hardware system is presented with a description of the software system on our platform. Tasks communication between the two cores is realized using the DSP driver. The system bootloader and the DSP bootloader are described in detail. The implementation of the MPEG-4 video decoder has been realized on the presented system. Higher speed can be achieved and less power is needed for MPEG-4 video processing on the dual-core platform. This dual-core system can be applied to 3G wireless communication, robot control and vision systems.
