Disclosed is a method for sharing the storage structure used for the execution of graphics instructions in the high and low priority ring buffer. The command parser uses a DMA mechanism for fetching commands from memory. Benefits include memory fetches that are bunched together to improve memory access performance. Also, the pre-fetched commands from memory are stored in a single FIFO for both low and high priority buffers.
