一種視訊編碼器之記憶體管理方法,用以對一參考畫框之複數畫素值進行排序,該方法包含下列步驟:(a)根據一特定位元深度,將每一畫素值分割為複數個位元區段,其中,每一位元區段對應一位元重要程度;(b)將該等畫素值中,對應相同之位元重要程度的位元區段排列在一起,以形成複數個特定位元深度平面;及(c)將該等特定位元深度平面儲存至該視訊編碼器之一參考畫框記憶體。
In a method and system for writing a reference frame having multiple pixels into a reference frame memory, the pixels of the reference frame are sampled to obtain a plurality of representative pixels. A multi-bit pixel value of each of the representative pixels is divided into a number (N) of bit sections, each corresponding to one of a number (N) of different bit significance levels, based on a bit depth, where N is associated with the bit depth. The bit sections of the pixel values of the representative pixels having the same bit significance level are arranged together to form a number (N) of bit depth planes each including the bit sections that have a corresponding one of the bit significance levels. The bit depth planes are stored in the reference frame memory.
