METHOD AND APPARATUS FOR DYNAMIC, MULTI-SPEED BUS ARCHITECTURE WITH SPEED MESSAGES INDEPENDENT OF DATA SIGNAL TRANSFERS

摘要

A method for simultaneous transmission of signals on a bus having at least two nodes. The present invention provides a method and apparatus for driving a common node current on each of two lines of a twisted pair. The present invention also includes a method and apparatus for applying a voltage bias to each of the signal lines and then comparing the voltage bias with a first voltage derived from a second coupling of the first and second signal lines. The present invention also includes a method and means for generating a response signal corresponding to the voltage difference between the first voltage and the voltage bias.
