Method and apparatus for memory management of video images

A computer-readable medium having stored thereon a set of instructions, the set of instruction, which when executed by a processor, cause the processor to perform a method comprising:

• receiving a quantized block of an image;
• performing inverse quantization on the quantized block to generate a frequency spectrum for the quantized block;
• performing inverse discrete cosine transformation of the quantized block using the frequency spectrum to generate a decoded block;
• repeating the receiving, decoding, performing and performing for a plurality of encoded blocks, such that a plurality of decoded blocks are formed;
• motion compensating the plurality of blocks as a group thereby generating a plurality of motion compensated (MC) blocks and;
• repeating the receiving, decoding, performing, performing, repeating and motion compensating for each quanitized block of the image.

A method, comprising:

• receiving a block of a color components of an image in a mixed format of a packed format and a planar format;
• converting the block of color components in the mixed format into a format as one of the packed format and the planar format;
• repeating the receiving and the converting for a plurality of blocks of color components, wherein the plurality of blocks of color components include four blocks of color components;
• storing the plurality of blocks of color components in a format as of the planar format and the packed format;
• repeating the receiving, the converting and the storing for each block of color components of the image;
• and
• writing pixel data of the four blocks as a group and in a sequential manner to a frame buffer, such that prior to being burst written to the frame buffer, the pixel data is temporarily held in an entry of a write-combining (WC) buffer, thereby eliminating partial writes from the WC buffer.
