Abstract
A computer system measures bus signal distortion and then adjusts certain characteristics of the signal transmitted over the bus, or adjusts other characteristics of the bus or the load on the bus so that signal distortion is reduced. Distortion characteristics that may be measured include signal voltage overshoot and undershoot, and data setup and hold times. Characteristics of the signal and the system that may be adjusted include changing the slew rate of the signal, changing the data setup and hold times, and changing the load impedance on the bus.
