  本論文主要的研究是在德州儀器公司出產之DSC系統單晶片,設計出一個適合於嵌入式系統下之MPEG-4視訊解碼韌體系統。欲在DSP端實現本系統必須克服嚴格記憶體限制、平行化及加速指令效率等問題。本系統的實現,首先把關鍵的程式改以組合語言撰寫,接著使用系統單晶片中的共工處理器來加速,並利用硬體與記憶體的平行化,以達到即時解碼的效能,最後再結合網路系統來實現一個網路MPEG-4視訊點播系統。實驗結果顯示網路MPEG-4視訊點播系統在CIF與QVGA影像大小下可達到即時解碼的效能。
  In this thesis, the DSC System-on-a-Chip (SoC) manufactured from Texas Instruments (TI) is our mainly research, and design a firmware system of the MPEG-4 video decoder suitable for a embedded system. When implement this system at DSP side, we encounter three problems and have to overcome, such as strictly limited memory space, parallelization, and the efficiency of accelerative instructions.In the beginning, the crucial C codes in our system were rewritten as assembly code. Then, several coprocessors of the SoC help us to accelerate the MPEG-4 Simple Profile decoder, and parallelizing hardware and memories to achieve real-time decoding. Finally, we combine a network to realize the Internet MPEG-4 video on demand player. The simulation results show that performance of Internet MPEG-4 video on demand player reaching the CIF and QVGA size images in real-time decoding.
