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.
