Abstract:
1. In a graphics pipeline of a graphics processor, a method for latency buffered scoreboarding, comprising: receiving a graphics primitive for rasterization in a raster stage of a graphics processor; rasterizing the graphics primitive to generate a plurality pixels related to the graphics primitive; storing an ID to account for an initiation of parameter evaluation for each of the plurality of pixels as the pixels are transmitted to a subsequent stage of the graphics processor, wherein the ID is generated by a raster unit; buffering fragment data resulting from the parameter evaluation for each of the plurality of pixels by the subsequent stage; comparing the ID and the fragment data from the buffering; accounting for a completion of parameter evaluation, by using a scoreboard clear packet, for each of the plurality of pixels when the ID and the fragment data match and as the fragment data is written to a memory, wherein the scoreboard clear packet comprises information that identifies in-flight fragments that have just been launched, and wherein the scoreboard clear packet is an ID generated by the raster unit.
