Abstract
A method of data storage includes associating delta colour compression DCC metadata with one or more tiles of graphics data, selecting one or more such tiles that are uniform in colour and hence can be accurately represented by the DCC metadata for that tile, and replacing some or all of the graphics data in one or more selected tiles with different data.
Claims13
A method of data storage, comprising:
- associating delta colour compression DCC metadata with one or more tiles of graphics data;
- selecting one or more such tiles that are uniform in colour and hence can be accurately represented by the DCC metadata for that tile;
- and
- replacing some or all of the graphics data in one or more selected tiles with different data, wherein the different data relates to one or more of:
- i. additional or alternative graphics data;
- ii. image processing;
- and
- iii. one or more processes other than image processing.
A non-transitory, computer readable storage medium containing a computer program comprising computer executable instructions, which when executed by a computer system, cause the computer system to perform a method of data storage by carrying out actions, comprising:
- associating delta colour compression DCC metadata with one or more tiles of graphics data;
- selecting one or more such tiles that are uniform in colour and hence can be accurately represented by the DCC metadata for that tile;
- and
- replacing some or all of the graphics data in one or more selected tiles with different data, wherein the different data relates to one or more of:
- i. additional or alternative graphics data;
- ii. image processing;
- and
- iii. one or more processes other than image processing.
A data storage system, comprising:
- memory for storing delta colour compression DCC metadata in association with one or more tiles of graphics data;
- a selection processor adapted to select one or more such tiles that are uniform in colour and hence can be accurately represented by the DCC metadata for that tile;
- and
- an update processor adapted to replace some or all of the graphics data in one or more selected tiles with different data,
- wherein the different data relates to one or more of:
- i. additional or alternative graphics data;
- ii. image processing;
- and
- iii. one or more processes other than image processing.
