Title: Reducing errors in data by dynamically calibrating trigger point thresholds

Abstract: Methods, systems, computer readable media and means for reducing errors in data caused by noise are provided. In some embodiments of the present invention, circuitry of the device receives timing data from one or more other circuitries and identifies noiseless periods from the timing data. The circuitry then actively adjusts the trigger point threshold of data being transmitted to and/or from the circuitry only during the noiseless periods. The circuitry subsequently monitors the timing data to identify noise periods. In response to identifying a noise period, the device ceases to adjust the trigger point threshold until the noise period is over.
