Abstract
Embodiments of the present invention relate to displaying images from memory. A plurality of pixel attributes are retrieved from memory in a single memory transaction. At least one attribute corresponds to one scan line of a display and another attribute corresponds to another scan line of the display. A portion of one scan line using the corresponding pixel attribute is displayed. The pixel attributes corresponding to another scan line is stored in a buffer.
Claims29
A method for displaying images, the method comprising:
- retrieving a plurality of pixel attributes from memory in a single memory transaction, wherein an attribute of said plurality of attributes corresponds to a pixel in one scan line of a display and an attribute of said plurality of attributes corresponds to a pixel in another scan line of the display;
- displaying a portion of one scan line using the corresponding pixel attribute;
- and storing the pixel attribute corresponding to another scan line in a buffer.
Apparatus for displaying images, the apparatus comprising:
- a memory to store pixel attribute information;
- a buffer to store pixel attribute information of a next scan line;
- and
- a display engine, wherein in a single memory transaction the display engine to retrieve pixel attribute information from the memory, display at least a portion of one scan line using attribute information of the one scan line and store attribute information of the next scan line in the buffer.
A scan line driving method, comprising:
- retrieving attribute information of each pixel in a first scan line and an attribute information of a pixel in another scan line from a memory in a memory transaction;
- and
- storing the attribute information of a pixel in the another scan line until the first scan line is displayed.
A graphics system, comprising:
- a memory populated by a plurality of storage entries having a length sufficient to store image attribute information of a plurality of pixels, said storage entries located in consecutive memory locations;
- and
- a graphics processor coupled to the memory, the graphics processor comprising a display engine and a scan line buffer, the display engine to retrieve from memory those storage entries associated with a current scan line and storage entries associated with other than the current scan line in a single memory transaction, the scan line buffer adapted to store image attribute information retrieved by the display engine and associated with scan lines other than the current scan line.
