Abstract:
A bus system for use with addressable slave devices comprising:a global bus comprising uni-directional signal lines, the global bus having a first end and a second end; a master device for transmitting data to and receiving data from the global bus; first and second global bus terminators coupled to the first and second ends of the global bus, respectively; and one or more subsystems connected in parallel to each other and to the master device via the global bus, each subsystem including: a local bus; one or more slave devices coupled to the local bus; a write buffer that receives incoming signals from the master device via the global bus and transmits the incoming signals to the one or more slave devices via the local bus; and a read buffer that receives outgoing signals from the one or more slave devices via the local bus and transmits the outgoing signals to the master device via the global bus.
