    摘要: A bus system for use with addressable memory has a global bus of uni-directional signal lines. The global bus has a first end and a second end. A master device transmits data to and receives data from the global bus. First and second global bus terminators are coupled to the first and second ends of the global bus, respectively. One or more subsystems are connected in parallel to each other and to the master device via the global bus. Each subsystem includes 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.
