Abstract:
One embodiment of the present invention sets forth a system for computing and error checking configuration parameters related to raster image generation within a graphics processing unit. Input parameters are validated by a hardware-based error checking engine. A hardware-based pre-calculation engine uses validated input parameters to compute additional private configuration parameters used by the raster image generation circuitry within a graphics processing unit.
