ABSTRACT:
A special bridge device provides a level of isolation between two independent but compatible bus environments such that only addresses and transactions directed to the other environment are passed through, together with associated data and control information. The device includes address and transaction remapping between the two environments.
During an initialization phase, this device presents itself to the host system as a simple bus device. In one preferred embodiment, the special bridge presents itself as a mass storage or memory device. The host computer performs the minimal setup for such a device. During initialization of the second bus environment, the special bridge device again presents itself only as a simple device, and preferably is not presented as a bus device to the second system at all.
During system operation, the special bus device passes selected addresses, transactions, and data between the two bus environments but in general allows each bus environment to operate independently of the other.
