  • Peripheral component interconnect gateway controller
    Patent number: 5848252
    Abstract: A gateway controller (100) for facilitating the exchange of information between PCI busses (101,103). The controller (100) may comprise a single printed wiring board (301) or two printed wiring boards (201,203) connected by cable (205). Busses (101, 103) are physically isolated from one another for security or other reasons.This technique provides for controlled communication capability which does not require direct linking of two subsystem buses. This technique also provides for a method of transparent communication between subsystems. This gateway controller (100) allows data control while providing bus security and physical isolation of communication buses.
