WUSB burst acknowledgment management

1 . A method for processing data in accordance with protocol specifications, comprising the steps of:

determining a beginning transmit window;

unwrapping the beginning transmit window;

determining an end receive window;

unwrapping the end receive window;

normalizing the unwrapped end receive window; and

comparing the unwrapped beginning transmit window and the normalized end receive window;

whereby an acknowledgement segment is generated based upon the comparison.

2 . The method of claim 1 , wherein the unwrapping steps further comprise the steps of:

placing a first bit of a burst sequence of the beginning transmit window or the end receive window at a predetermined location of a bit array.

3 . The method of claim 1 , wherein the normalizing step further comprises the steps of:

(a) determining whether a maximum sequence number bit has been set;

(b) determining whether a low bit of the end receive window has been set if it is determined that the maximum sequence number bit has been set;

(c) employing a number shift to the end receive window is it is determined that the low bit of the end receive window has been set;

(d) replacing the end receive window with a number shifted end receive window;

(e) repeating steps (b)-(d) until it is determined in step (b) that the low end bit of the end receive window has not been set; and

(f) outputting the unwrapped end receive window

4 . The method of claim 1 , further comprising the step of writing the acknowledge segment to a data buffer.

5 . The method of claim 1 , wherein the steps are repeated for each of a plurality of transaction data making up part of a data transfer.

6 . A system for processing data in accordance with protocol specifications, comprising:

a processor, the processor adapted to determine a beginning transmit window, unwrap the beginning transmit window, determine an end receive window, unwrap the end receive window, normalize the unwrapped end receive window; and compare the unwrapped beginning transmit window and the normalized end receive window;

whereby an acknowledgement segment is generated based upon the comparison.

7 . The system of claim 6 , wherein the processor is further adapted to:

placing a first bit of a burst sequence of the beginning transmit window or the end receive window at a predetermined location of a bit array.

8 . The system of claim 6 , wherein the processor is further adapted to:

(a) determine whether a maximum sequence number bit has been set;

(b) determine whether a low bit of the end receive window has been set if it is determined that the maximum sequence number bit has been set;

(c) employ a number shift to the end receive window is it is determined that the low bit of the end receive window has been set;

(d) replace the end receive window with a number shifted end receive window;

(e) repeat the processing of steps (b) - (d) until it is determined in step (b) that the low end bit of the end receive window has not been set; and

(f) output the unwrapped end receive window

9 . The system of claim 6 , wherein the processor is further adapted to write the acknowledge segment to a data buffer.

10 . The system of claim 6 , wherein the processor is further adapted to repeat the processing for each of a plurality of transaction data making up part of a data transfer.

11 . A computer program embodied in a computer readable memory for processing data in accordance with protocol specifications, the computer program comprising instructions for performing the steps of:

determining a beginning transmit window;

unwrapping the beginning transmit window;

determining an end receive window;

unwrapping the end receive window;

normalizing the unwrapped end receive window; and

comparing the unwrapped beginning transmit window and the normalized end receive window;

whereby an acknowledgement segment is generated based upon the comparison and stored to a data buffer.

12 . The computer program of claim 11 , wherein the unwrapping steps further comprise the steps of:

placing a first bit of a burst sequence of the beginning transmit window or the end receive window at a predetermined location of a bit array.

13 . The computer program of claim 11 , wherein the normalizing step further comprises the steps of:

(a) determining whether a maximum sequence number bit has been set;

(b) determining whether a low bit of the end receive window has been set if it is determined that the maximum sequence number bit has been set;

(c) employing a number shift to the end receive window is it is determined that the low bit of the end receive window has been set;

(d) replacing the end receive window with a number shifted end receive window;

(e) repeating steps (b)-(d) until it is determined in step (b) that the low end bit of the end receive window has not been set; and

(f) outputting the unwrapped end receive window

14 . The computer program of claim 11 , wherein the steps are repeated for each of a plurality of transaction data making up part of a data transfer.
