Abstract:
A graphics system comprising:a frame buffer, wherein the frame buffer includes a first set of one or more memory banks, a second set of one or more memory banks, and a cache, wherein the frame buffer is configured to load data from the first set into the cache in response to receiving a cache fill request targeting the first set, wherein the first set is accessible independently of the second set; and a frame buffer interface coupled to the frame buffer, wherein the frame buffer interface comprises a first cache fill request queue configured to store one or more cache fill requests targeting the first set and a second cache fill request queue configured to store one or more cache fill requests targeting the second set; wherein the frame buffer interface is configured to select a next cache fill request to process by: selecting a next cache fill request from the first cache fill request queue, if the first set is not currently being accessed or selecting the next cache fill request from the second cache fill request queue, if the first set is currently being accessed and the second set is not currently being accessed.
