Running disparity computation predictor

摘要

A running disparity computation predictor is configured to analyze a frame of data, a control value, and an input tracking value and generate a predicted output tracking value. A frame selector is configured to generate an encoded frame of data based on this predicted output tracking value. A frame insertion module is configured to insert the encoded frame of data into a data stream wherein the predicted output tracking value matches an output tracking value generated by the data stream. This combination of elements can bypass an encoder built into a Hard IP block or proprietary hardware when the running disparity value is required to select control words.

1. A method comprising:
receiving a frame of data of a data stream, a control value, and an input tracking value; analyzing the frame of data, the control value and the input tracking value to generate a toggle value representing whether the input tracking value should be toggled; generating a predicted output tracking value based on the input control value and the toggle value; selecting one of a positive disparity frame or a negative disparity frame to be a selected frame; and encoding a disparity of a control word to be inserted into the data stream, the encoded disparity of the control word being based (i) the predicted output tracking value and (ii) the selected frame.
