ABSTRACT:
A bus interface system and method for communication between different computer components having buses with different speeds, data widths, or protocols. A first state machine communicates with the first bus and a second state machine communicates with the second bus. Each of the buses communicates with a data storage device. The first and second state machines are in selective communication using an asynchronous handshaking protocol, whereby data is transferred between said first and second buses. The handshaking protocol comprises an asynchronous request signal from the first bus requesting a data transfer and an asynchronous reply signal from the second bus indicating that data has been sent or is available.
