COMMUNICATION CHANNEL CALIBRATION FOR DRIFT CONDITIONS

摘要

A method provides for execution of calibration cycles during normal operation of the communication channel (1002). A calibration cycle includes de-coupling the normal data source (1010) from the transmitter (1003) and supplying a calibration pattern in its place. The calibration pattern is received from the communication link using the receiver (1004) on the second component (1001). A calibrated value of a parameter of the communication channel is determined in response to the received calibration pattern. The steps involved in calibration cycles can be reordered to account for utilization patterns of the communication channel (1002). For bidirectional links, calibration cycles are executed which include the step of storing received calibration pattern on the second component (1001), and retransmitting such calibration back to the first component (1000) for use in adjusting parameter of the channel at first component (1000).
