ASYNCHRONOUS INTERFACE

摘要

of the Invention An asynchronous interface is presented which enables the transfer of information between a set of devices having a wide range of operating speed. Each device can enter a Controller active state in which it sources command frames to control the loop operation. Each device can also enter a Talker active state in which it sources Data frames on a Listener active state in which it received Data frames. The transfer of frames is coordinated by a set of handshakes which enable the frames to be transferred in an asynchronous manner.
