Abstract
Row addressing circuitry for implementing random row selection, pre-writes, and bi-directional scrolling includes a plurality of decoders, each connected to an address bus, each having a decoder enable input, and each producing row enable signals for rows of a pixel array. Row enable information for each row from each decoder is logically combined together to produce composite row drive information. Beneficially, each decoder is connected to the same address bus, and each decoder enable signal is produced from a common controller. By using the row enable signals, in synchronization with address information on the address bus, the correct row drive information, such as pre-writes or image information, is applied to each of pixels. Bi-directional scrolling can be implemented by enabling two rows to accept the same image information.
