Method and apparatus for interleaving read and write accesses to a frame buffer

Some embodiments of a data channel that interleaves read and write access to a frame buffer include a bit-plane storage device, a single frame buffer, a data controller and a digital pixel display. Transferring data through the single frame buffer by interleaving reads and writes includes (1) alternately writing to the frame buffer and reading from the frame buffer portions of each bit-plane of a sequence bit-plane data; and (2) writing to said frame buffer so as to replace each said portion of a bit-plane in the frame buffer with a corresponding portion of a next bit-plane. By interleaving read and write accesses, a single frame buffer and less interface logic are necessary to transfer data from a storage device to a digital pixel display. In a three channel digital color pixel imaging device, this reduces the number of frame buffer SDRAM units from six to three, and significantly reduces the overall cost associated with implementing data flow through the data storage and frame buffer blocks.
