Method and apparatus for storing and displaying video image data in a video graphics system

A method for processing image data in a video graphics system comprising:

• receiving image data, wherein the image data includes at least three color components, wherein each of the color components is received in a plane;
• storing the image data in a memory, wherein storing further includes interleaving a portion of the at least three color components into an interleaved plane such that color components of the interleaved plane are grouped locally, wherein the portion is determined based on utilization of the color components;
• retrieving the image data from the memory, wherein portions of the interleaved plane are retrieved such that locally grouped color components are retrieved simultaneously;
• and
• processing the image data, wherein processing utilizes the color components of the interleaved plane.

A method for displaying video image data comprising:

• receiving a data stream, wherein the data stream includes compressed video image data;
• parsing the data stream to separate the compressed video image data from other stream data;
• decompressing the compressed video image data to produce video image data, wherein video image data includes a luminosity plane, a first color plane and a second color plane, wherein the luminosity plane is larger than the first and second color planes;
• packing members of the first and second color planes to form color pairs, wherein a plurality of color pairs form a color line;
• interleaving each of the color lines with at least one luminosity line to produce an interleaved plane;
• storing the interleaved plane in a memory;
• retrieving portions of the video image data from the interleaved plane in groups of image data;
• generating video output data based on retrieved groups of image data, wherein luminosity and color values within the groups of image data are utilized together to produce the video output data.

A video image processing circuit comprising:

• a memory, wherein the memory stores video image data;
• an interleaving block operably coupled to the memory, wherein the interleaving block is adapted to receive a video data stream that includes image data, wherein the image data includes a luminosity plane, a first color plane, and a second color plane, wherein the interleaving block interleaves the first and second color planes with the luminosity plane to form an interleaved plane, wherein the interleaved plane is stored in the memory;
• and
• a display output engine operably coupled to the memory, wherein the display output engine retrieves interleaved portions of the interleaved plane from the memory and generates a display output based on the interleaved portions, wherein the interleaved portions include selected portions of the luminosity plane and the first and second color planes that are used together in generating the display output.

A method for processing image data in a video graphics system comprising:

• receiving image data, wherein the image data includes at least two color components, wherein each of the color components is received in a plane;
• storing the image data in a memory, wherein storing includes interleaving a portion of the at least two color components into a packed plane such that color components of the packed plane are grouped locally, wherein the portion is determined based on utilization of the color components;
• retrieving the image data from the memory, wherein portions of the packed plane are retrieved such that locally grouped color components are retrieved simultaneously;
• and
• processing the image data, wherein processing utilizes the color components of the packed plane.
