Abstract
A system is provided for storing pixel data associated with a predetermined pixel region. The system is configured to store pixel data in a predetermined block of memory along with a fill check bit indicative of whether or not values for each pixel within the pixel region are the same as a predetermined reference pixel. The system also provides for the generation of a stream of pixel data corresponding to a pixel region by outputting a value for a pixel within the region that is equal to the reference pixel when the fill check bit is set.
Claims23
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 to associate a predetermined reference pixel with said pixel region;
- and
- said controller is further configured to store pixel data representing values of said predetermined 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 said data representing said predetermined reference pixel.
A graphics system for processing pixel data that is associated with a predetermined pixel region, the system comprising:
- memory;
- controller configured to check a fill check bit that is associated with a pixel region, to determine whether it is set to indicate that all pixel data within said pixel region is the same as a predetermined reference pixel that is associated with said pixel region;
- and
- said controller is further configured to retrieve said reference pixel data from said memory and write said reference pixel data to a sequential block of memory associated with said pixel region for each pixel within said pixel region, where said fill check bit indicates that all pixel data within said pixel region is the same as said reference pixel data.
A method of processing pixel data associated with a predetermined pixel region, said method comprising the steps of:
- identifying all pixel data associated with a predetermined pixel region to be stored to memory;
- associating a predetermined reference pixel with said pixel region;
- storing pixel data for 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 said predetermined reference pixel.
A method of processing pixel data associated with a predetermined pixel region, said method comprising the steps of:
- checking a fill bit associated with said pixel region to determine whether it is set to indicate that all pixel data within said pixel region is the same as a predetermined reference pixel associated with said pixel region;
- and
- retrieving said reference pixel data from memory for each pixel within said pixel region where said fill check bit indicates that all pixel data within said pixel region is the same as said reference pixel data.
