Method and apparatus for serial bus elements of an hierarchical serial bus assembly to electrically represent data and control states to each other

摘要

Circuitry and complementary logic are provided to a bus controller, a number of 1:n bus signal distributors, and a number of bus interfaces of an hierarchical bus assembly for electrically representing data and control states each other. The hierarchical serial bus assembly is used to serially interface a number of isochronous and asynchronous peripherals to the system unit of a computer system. The serial bus elements are interconnected to each other using low cost two wire signal cable. Electrical signals are propagated between the serial bus elements in a differential manner. These circuitry and complementary logic of the serial bus elements jointly implement inference of data and control states from the states and/or durations of the propagating electrical signals.
