ABSTRACT:
A memory for a graphics processor is provided. The memory includes a write first-in-first-out (FIFO) region of the memory for receiving pixel data, and a read FIFO region for accessing the pixel data received into the memory through the write FIFO. The memory has a memory controller having write assembly logic for rearranging the pixel data received by the write FIFO for storage in the memory. The write assembly logic is configured to write data representing a first pixel and a second pixel across a plurality of data segments in the memory, where corresponding bit locations for the data representing the first pixel and the data representing the second pixel are contiguous. A graphics controller having the memory and a method for preventing data corruption from being displayed during an underflow are included.
