Apparatus and method for asynchronously controlling data transfers across long wires

摘要

One embodiment of the present invention provides a system that asynchronously controls the sending of data items from a sender to a receiver. The system includes a data path between the sender and the receiver, a first control path between the sender and the receiver, and a second control path between the sender and the receiver. The first control path and the second control path alternately control the asynchronous transmission of consecutive data items on the data path between the sender and the receiver.
