ABSTRACT:
A system and method for planarizing n-bit display data into m-bit data. The system includes a plurality of input terminals, a plurality of output terminals, and a first storage bank having a bit-depth less than m. In one embodiment, the first storage bank is a bi-directional shift register including a clock input terminal, for receiving a data shift signal, and a direction terminal for receiving a direction control signal. In a particular embodiment, the bi-directional shift register includes a plurality of flip-flops and a plurality of multiplexers, both arranged in a rectangular array of columns and rows. Optionally, the system includes a second storage bank, and data is shifted into one storage bank while data is being shifted out of the other storage bank.
