視訊編碼插補點中降低運算量與記憶體存取次數之方法

To Decrease the Computation Load and Memory Access Frequency during Interpolation of Video Coding

摘要


本論文主要提出一個方法,用以解決視訊處理(編碼或解碼)中的補差點(interpolation)計算量問題,以及運算過程中到外部記憶體存取(access)資料的次數問題。一般在視訊處理中的動態補償(motion compensation)其計算量佔整個系統總運算量相當大的比重,其中以interpolation佔的運算量最重。但由於在自然影像中,其畫面內之影像彼此的關連性(correlation)很強;因此利用此一特性,本論文提出一個方法,將已計算過的interpolation數值先予以儲存起來,並搭配一個記憶體位址旋轉(Memory Address Ration: MAR)方式來管理記錄這些interpolation數值,以達到降低計算量和記憶體存取次數之目的。

This paper proposes a method to address the computation load and memory access frequency problems during interpolation for video processing (coding or decoding). The motion compensation process in video processing is computationally intensive and takes considerable computation time of the system, while the interpolation step in the process incurs the heaviest computation load. Exploiting the characteristics of strong correlation between natural images in a frame, this paper proposes a patented method that stores the computed interpolation values and then manages the values using memory address rotation (MAR) technique to decrease the computation load and memory access frequency.
