Claims20
A data processing system, the system comprising:
- a data processing circuit operable to receive a set of data having at least a first fragment and a second fragment, wherein the first fragment includes an initial alignment data and the second fragment includes a subsequent alignment data;
- a zero phase start calculation circuit operable to calculate a zero phase start output based upon the initial alignment data;
- a distance counter operable to count a distance between elements of the initial alignment data and corresponding elements of the subsequent alignment data;
- and
- a zero phase start alignment circuit operable to modify a portion of the zero phase start output to yield a modified zero phase start output based at least in part on the distance, wherein processing of the subsequent alignment data uses the modified zero phase output.

- a second zero phase start calculation circuit operable to calculate a second zero phase start output based upon the initial alignment data from the second set of data;
- a zero phase start output combining circuit operable to combine the first zero phase start output and the second zero phase start output to yield a combined zero phase output
- a distance counter operable to count a distance between elements of the initial alignment data and corresponding elements of the subsequent alignment data;
- and
- a zero phase start alignment circuit operable to modify a portion of the combined zero phase start output to yield a modified zero phase start output based at least in part on the distance, wherein processing of the subsequent alignment data uses the modified zero phase output.
