Bridge supporting multiple interfaces access to subsystem

Abstract:

A device includes a processor, an SBI, and a plurality of interfaces. The processor is configured to manage operations of the device. The SBI is coupled to the processor. The plurality of interfaces is associated with the SBI. The interfaces of the plurality of interfaces have different interface protocol from one another. The SBI is configured by the processor and the configuration of the SBI activates one interface of the plurality of interfaces at any given time. The active interface that is selected from the plurality of interfaces and a host have a same interface protocol. The active interface is configured to receive host data from the host. The SBI is configured to generate a flag for the processor in response to the active interface receiving the host data. The SBI is configured to transmit device data to the host.
