ABSTRACT:
A system and method for a row forwarding of pixel data in a 3-D graphics pipeline. Specifically, in one embodiment a data write unit capable of row forwarding in a graphics pipeline includes a first memory and logic. The first memory stores a plurality of rows of pixel information associated with a pixel. The plurality of rows of pixel information includes data related to surface characteristics of the pixel and includes a first row, e.g., a front row, and a second row, e.g., a rear row. A data write unit includes first logic for accessing a portion of the second row and for storing data accessed therein into a portion of the first row. The data write unit also comprises logic for recirculating the plurality of rows of pixel information to an upstream pipeline module for further processing thereof.
