20080204473 | METHODS AND SYSTEMS FOR LEGACY GRAPHICS EMULATION - Embodiments of the present invention provide a seamless way to emulate legacy graphics processing on modern graphics hardware. In particular, in some embodiments, the present invention provides a way for modern GPUs to emulate the bitwise operations and rendering processes of previous generations of graphics hardware. The present invention utilizes a novel pixel shader program. The pixel shader program provides a texture lookup functionality that compensates for any missing bitwise functionality. When a bitwise operation is requested, the system will copy out the destination area to a temporary image. This temporary image is fed to the pixel shader program along with a precomputed texture. The texture is precomputed by the CPU for the various bitwise operations and acts as a lookup table for the requested operation. With the temporary image and precomputed texture, the shader program on the GPU can then emulate the legacy graphics operations seamlessly. Accordingly, all temporaries, and the emulation of the bitwise operations themselves are done using the three dimensional engine of the GPU. | 2008-08-28 |
