Technique for providing improved signal integrity on computer systems interface buses

摘要

An interface system for transmitting a pulse waveform signal between a host computer and a plurality of peripheral units wherein such signal is transmitted on a dedicated bus, the peripheral units being connected to the bus in selected groups thereof. Each group has a buffer unit connected between the group of units and the host unit, the buffer unit including circuitry for providing signal transmission in only one direction, for controlling the final signal level of the signal, and for controlling the slope of the trailing edge of the signal so that signal degradation is minimized.
