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

摘要

An exemplary data arrangement method for a picture includes at least the following steps: obtaining pixel data of a plurality of first N-bit pixels of the picture; and storing the obtained pixel data of the first N-bit pixels in a plurality of M-bit storage units of a first buffer based on a raster-scan order of the picture, wherein M and N are positive integers, and M is not divisible by N. Besides, at least one of the M-bit storage units is filled with part of the obtained pixel data of the first N-bit pixels, and the first N-bit pixels include at least one pixel divided into a first part stored in one of the M-bit storage units in the first buffer and a second part stored in another of the M-bit storage units in the first buffer.

1. A data arrangement method, comprising:
obtaining pixel data of a plurality of first N-bit pixels of a picture; and storing, by a buffer controller, the obtained pixel data of the first N-bit pixels in a plurality of M-bit storage units of a first buffer based on a raster-scan order of the picture, wherein at least one of the M-bit storage units is filled with part of the obtained pixel data of the first N-bit pixels, M and N are positive integers, M is not divisible by N, and the first N-bit pixels include at least one pixel divided into a first part stored in one of the M-bit storage units in the first buffer and a second part stored in another of the M-bit storage units in the first buffer; wherein the first N-bit pixels correspond to one of luma pixels and chroma pixels of the picture.
