Method and apparatus for arranging pixels of picture in storage units each having storage size not divisible by pixel size

摘要

A buffer write method for a buffer, including a plurality of M-bit storage units, has following steps: obtaining pixel data of a plurality of first N-bit pixels of a picture; calculating a corresponding start address of the buffer for the pixel data of the first N-bit pixels; and storing the first N-bit pixels of the picture according to the calculated start address of the buffer in the M-bit storage units by a buffer controller. The storing step includes fully storing at least one of the first N-bit pixels in one of the M-bit storage units storage units, wherein M and N are positive integers, and M is not divisible by N.
