ABSTRACT:
A system and method for processing graphics data which improves utilization of read and write bandwidth of a graphics processing system. The graphics processing system includes an embedded memory array having at least three separate banks of single ported memory in which graphics data are stored in memory page format. A memory controller coupled to the banks of memory writes post-processed data to a first bank of memory concurrently with reading data from a second bank of memory. A synchronous graphics processing pipeline processes the data read from the second bank of memory and provides the post-processed graphics data to the memory controller to be written back to the bank of memory from which the pre-processed data was read. The processing pipeline is capable of concurrently processing an amount of graphics data at least equal to the amount of graphics data included in a page of memory. A third bank of memory is precharged concurrently with writing data to the first bank and reading data from the second bank in preparation for access when reading data from the second bank of memory is completed.
