ABSTRACT:
A multiple device serial data bus and signalling scheme is described. The serial data bus allows for inter-peripheral communication at a data rate established by a bus control unit. Clocking information is extracted from data communicated from the bus controller to the peripheral devices. Additional conductors for clock information are not required. In addition an arbitration scheme is provided to eliminate bus contention if several units request service simultaneously. The multiple device serial data bus is utilized on an as required basis and may communicate information at a variety of data rates.
