Reducing errors in data by dynamically calibrating trigger point thresholds
First Claim
1. A method of calibrating a trigger point threshold of data being transferred to first circuitry of an electrical device from second circuitry of the electrical device, comprising:
- actively adjusting the trigger point threshold, wherein the trigger point threshold determines where bits of the data being transferred from the first circuitry to the second circuitry switch value;
determining whether noise is present;
in response to determining the noise is present, ceasing to adjust the trigger point threshold;
determining whether the noise has ceased; and
in response to determining that the noise has ceased, actively adjusting the trigger point threshold.

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.
