Abstract
A method and apparatus are provided for a lighting system for graphics processing. Included is a plurality of input buffers adapted for being coupled to a transform system for receiving vortex data therefrom. The input buffers include a first input buffer, a second input buffer and a third input buffer. An input of the first buffer, the second input buffer and the third input buffer are coupled to an output of the transform system. Further included is a multiplication logic unit having a first input coupled to an output of the first input buffer and a second input coupled to an output of the second input buffer. An arithmetic logic unit has a first input coupled to an output of the second input buffer. The arithmetic logic unit further has a second input coupled to an output of the multiplication logic unit. An output of the arithmetic logic unit is coupled to the output of the lighting system. Next provided is a first register unit having an input coupled to the output of the arithmetic logic unit and an output coupled to the first input of the arithmetic logic unit. A second register unit has an input coupled to the output of the arithmetic logic unit. Also, such second register …
