ABSTRACT:
Systems and methods are provided for performing a BLT (BLock Transfer). In accordance with one embodiment, a method uses a texture-mapping subsystem to perform the BLT by configuring the texture-mapping subsystem with coordinate values corresponding to a block of pixels to be transferred. In accordance with another embodiment, an apparatus comprises logic for defining a texture map from a source segment of memory corresponding to a frame buffer, logic for configuring a texture-mapping subsystem with coordinate values corresponding to a first block of pixels on a display, logic for using a texture-mapping subsystem to apply the texture map defined by the configured coordinate values to a destination segment of memory corresponding to a second block of pixels on the graphic display, wherein the application of the texture map effects a BLT of the data from the first block of pixels to the second block of pixels.
