Abstract
A formatter and frame buffer unit (20) for a display system (10) that uses a spatial light modulator (16) to display data formatted in bit-planes. Formatters (21) convert multi-bit pixel data to bit-plane data. The frame buffer memory (25) is comprised of conventional DRAM devices. To allow the use of DRAMs, formatters (21) operate on a number of consecutive pixels, the number of pixels being sufficient for an extended page mode form of addressing the DRAMs.
