摘要: A method in system for latency buffered scoreboarding in a graphics pipeline of a graphics processor. The method includes receiving a graphics primitive for rasterization in a raster stage of a graphics processor and rasterizing the graphics primitive to generate a plurality pixels related to the graphics primitive. An ID stored 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. A buffer is used to store the fragment data resulting from the parameter evaluation for each of the plurality of pixels by the subsequent stage. The ID and the fragment data from the buffering are compared to determine whether they correspond to one another. The completion of parameter evaluation for each of the plurality of pixels is accounted for when the ID and the fragment data match and as the fragment data is written to a memory.

摘要: The invention is a method and apparatus for processing image data stored in a memory. A read interface circuit is coupled to the memory to transfer a patch of the image data from the memory to a buffer. A scale filter is coupled to the read interface circuit to scale the image data in the patch from the buffer. A receive circuit is coupled to the scale filter to re-organize the scaled image data.
