一種適用於視訊處理晶片組中移動評估的資料讀取之方法,視訊處理晶片組包括內部記憶體,且其耦接存有第一畫框的資料的外部記憶裝置。移動評估的資料讀取之方法之步驟首先將第二畫框分割成M�N個子畫框組,每一子畫框組中包括O�P個子畫框。且依據計算順序選擇各該子畫框組,已被選擇之子畫框組的資料被儲存於內部記憶體中。並計算已被選擇之子畫框組當中各子畫框的預測搜尋路徑。且決定預測讀取範圍,預測讀取範圍包括各子畫框之預測搜尋路徑。並根據預測讀取範圍,從第一畫框的資料中讀取比對資料。
A data reading method for motion estimation in a video processing chipset is provided. The video processing chipset is coupled to an external memory device, wherein a first frame is stored in the external memory device. In the data reading method, a second frame is first divided into M×N sub frame sets, wherein each of the sub frame sets includes O×P sub frames. Then, each of the sub frame sets is selected in a calculation sequence, wherein the selected sub frame set is stored into an internal memory. Next, a predicted search path of each sub frame in the selected sub frame set is calculated. Thereafter, a predicted reading range is determined, wherein the predicted reading range includes the predicted search paths of the sub frames. Finally, a comparison data is read from the first frame according to the predicted reading range.
