  • Bidirectional data buffer for a bus-to-bus interface unit in a computer system
    Patent number: 5644729
    Abstract: A method and system are provided for controlling data transfer between a system memory connected to a system bus and at least one input/output (I/O) device connected to an I/O bus in a computer system. The system bus is coupled to the I/O bus by a bus interface unit comprising a first pair of buffers connected in series between the I/O bus and the system bus, and a second pair of buffers connected in series between the I/O bus and the system bus and in parallel with the first pair of buffers. Each of the buffers in each of the pairs is used for bidirectional data transfer between the system bus and the I/O bus.
