Abstract
A system is provided for processing graphics data and outputting a stream of pixel data for display on an associated display device. The system is configured to store composed pixel data in a predetermined block of memory. The block of memory corresponds to a predetermined scan line of an associated display device.
Claims20
A system for generating a stream of composed pixel data comprising:
- memory;
- controller configured to store pixel data to said memory in a first block of sequential memory addresses;
- said controller is further configured to retrieve said pixel data from said memory, to compose said retrieved pixel data and store composed pixel data to a second predetermined block of sequential memory addresses;
- and
- said controller is further configured to retrieve said composed pixel data and output a stream of composed pixel data for display on an associated display device.
A method of generating a stream of composed pixel data, said method comprising the steps of:
- storing pixel data into a first memory location;
- retrieving said pixel data from said first memory location;
- composing said pixel data to produce composed pixel data;
- storing said composed pixel data to a second memory location;
- retrieving said composed pixel data from said second memory location;
- and
- outputting said composed pixel data.
A graphics system for processing pixel data associated with a predetermined pixel region comprising:
- memory;
- controller configured to identify pixel data associated with a predetermined pixel region that is to be stored to said memory;
- and
- said controller is further configured to associate a predetermined reference pixel with said pixel region and to store pixel data representative of said reference pixel to said memory and to set a fill check bit associated with said pixel region where the values of all pixels within said pixel region are the same as the value of said pixel data representative of said reference pixel.
A method of processing pixel data associated with a predetermined pixel region, said method comprising the steps of:
- identifying all pixel data that is associated with a predetermined pixel region and that is to be stored to memory;
- associating a predetermined reference pixel with said pixel region;
- storing pixel data representative of said reference pixel to memory;
- and
- setting a fill check bit associated with said pixel region to indicate that the values of all pixels within said pixel region are the same as the value of said pixel data representative of said reference pixel.
A method of processing pixel data that is associated with a predetermined pixel region, said method comprising the steps of:
- checking a fill bit that is associated with a pixel region to determine whether the fill bit is set to indicate that the values of all pixels within said pixel region are the same as the value of a predetermined reference pixel, said reference pixel being associated with said pixel region;
- and
- retrieving pixel data representative of said reference pixel from memory for each pixel within said pixel region, where said fill check bit indicates that the values of all pixels within said pixel region are the same as the value of said reference pixel.
