ABSTRACT:
Data input/output device for the display of information which is monolithically integrated in an application specific integrated circuit (ASIC). The device is principally constituted by a single memory which is divided into specific zones for the programs, the screen and the character generator. Access to the various specific zones is authorized by a single-memory bus line MB and is administered in accordance with a sequencing method provided by a microprogrammed sequencer programmed for flow regulation. Various devices can be added to the ASIC to make it possible to fully utilize the pass band of the memory, such as cache memory (CM), a FIFO register (FR), and line buffer registers (RB).
