dc.description.abstract在此論文中,我們設計了一個符合Ogg Vorbis標準的音訊解碼器。根據複雜度分析的結果,解碼的過程主要可分為兩部分:較複雜控制部分(如反量化),以及大量計算的部分(如IMDCT)。我們將控制的部分用軟體來實現,而大量計算的部分則用硬體來實現,利用軟硬體共同設計來完成整個Ogg Vorbis 音訊解碼系統。我們選擇Leon處理器及Xilinx Multimedia Board為發展平台來實現及驗證整個音訊系統。此平台為一個完整的SoC 設計環境。zh_TW
dc.description.abstractIn this thesis, we design an Ogg Vorbis audio system. According to the result of complexity analysis, decoding processes can be divided into two main groups, one contains high control complexity parts , e.g. inverse quantization, and the other contains high computation complexity parts, e.g. IMDCT. We implement the first group by C models, and design the second group by an FPGA system. Finally, we apply software/hardware co-design to implement the entire system. We choose the LEON processor and Xilinx Multimedia board, which is a complete environment for SoC design, to implement and verify the system.en_US
