Abstract: An apparatus and method for encoding data are disclosed that may allow for performing periodic calibration operations on a communication link. A controller may determine multiple possible values for a reference voltage used with the communication link based on an initial value. Calibration operations may be performed using each possible value, and the results of the operations scored based on the width of data eyes measured during the calibration operations. The controller may then select a new value for the reference voltage from the multiple possible values dependent upon the scores of each of the multiple possible values.

Abstract translation: 公开了一种用于编码数据的装置和方法，其可以允许在通信链路上执行周期性校准操作。 控制器可以基于初始值来确定与通信链路一起使用的参考电压的多个可能值。 可以使用每个可能的值执行校准操作，并且基于在校准操作期间测量的数据眼睛的宽度来评估操作的结果。 然后，控制器可以根据多个可能值中的每一个的分数从多个可能值中选择参考电压的新值。
