Abstract
Graphical memory access requests are routed to a plurality of bucket buffers. Filled bucket write buffers and empty bucket read buffers are efficiently emptied and filled respectively via a wide memory bus. The bucket sorting apparatus and method is used to increase the locality of memory references and pixel operations within a graphical rendering system. The increased locality increases graphical rendering performance and facilitates the usage of smaller z-buffers, larger tiles, and low-cost dynamic RAM within a graphics pipeline.
