H.264/AVC 是針對影像的新編碼技術. 傳統的數位訊號處理器無法有效率的處理這個新編碼技術. 研究結果顯示去區塊效應濾波器這個功能佔 H.264 解碼器 30% 的執行時間. 本篇論文中, 我們著重在針對去區塊效應濾波器來設計新的指令集以加速執行這個功能. 建構在 Starfish 數位訊號處理器的架構上, 我們針對去區塊效應濾波器設計出指令和架構. 實驗結果顯示, 針對去區塊效應濾波器的濾波程序部分. 我們所提出的指令可以改善 28.5% 的執行時間.

H.264/AVC is a new codec standard for video. A traditional DSP architecture is not e±cient enough for this new standard. The pro‾ling results show that Deblocking Filter
consumes up to 33% running time of H.264 decoder. In this thesis, we focus on designing new instructions to speed up Deblocking Filter. Based on a standard Star‾sh DSP, we
propose novel instructions and architecture for Deblocking Filter. In experiment result, we show that 28.5% improvement in computation time is achieved on Filter Processing part of Deblocking Filter by our new instructions.
