Implementation of the 3-view MPEG-2 encoder/decoder using the FastImage 1300 board

This paper presents an implementation of the 3-view moving picture experts group-2 (MPEG-2) encoder/decoder using the FastImage 1300 board with four Trimedia 1300 processors. First of all, we convert MPEG-2 algorithms into a Trimedia streaming software architecture (TSSA) for real-time implementation. For motion estimation, 32-bit DSP operations are used with two processors in parallel, with one processor performing encoding and decoding. To share data between processors for disparity estimation, we employ a semaphore (for synchronization), queue, and direct memory access (DMA). Experiments show that with the DSP board environment, the processing times of the implemented 3-view encoder and decoder are reduced by a factor of five and three, respectively, in comparison with the PC environment.
