摘要： A system and method for multi-protocol bus communications between integrated circuits is provided. An electronic system comprises an integrated circuit having an on-chip bus. The integrated circuit includes a master component and a first slave component, both coupled to the on-chip bus and communicate using a first on-chip bus protocol, a slave bus converter coupled to the on-chip bus, and a switch coupled to the slave bus converter and to the on-chip bus. The electronic system further comprising a second slave component coupled to the integrated circuit. The slave bus converter converts bus communications in the first on-chip bus protocol to a second on-chip bus protocol and the switch selectively couples the on-chip bus or the slave bus converter to the second slave component based on a bus select control signal.
