Abstract

The present application is directed to an electronic device that has a receiver configured to receive data from a second electronic device and identify potential sync header locations within a portion of the data by performing a mutually exclusive or (XOR) logic operation on a plurality of sequential pairs of bits of the data. Additionally, the receiver is configured to identify sync headers in the data by determining which of the potential sync header locations is shared in subsequent portions of the data.

Claims (49)

1. An electronic device comprising a receiver, wherein the receiver is configured to:

receive data from a second electronic device;

identify potential sync header locations within a portion of the data by performing a mutually exclusive or (XOR) logic operation on a plurality of sequential pairs of bits of the data; and

identify sync headers in the data by determining which of the potential sync header locations is shared in subsequent portions of the data.

2. The electronic device of claim 1 , wherein:

the data comprises one or more extended multiblocks;

each of the one or more extended multiblocks comprise at least one multiblock;

the at least one multiblock comprises a plurality of blocks; and

each block of the plurality of blocks comprises a sync header.

3. The electronic device of claim 2 , wherein the portion of the data comprises an entire block of the plurality of blocks.

4. The electronic device of claim 2 , wherein each block of the plurality of blocks comprises sixty-six bits of the data.

5. The electronic device of claim 2 , wherein the receiver is configured to align the one or more extended multiblocks by:

after identifying the sync headers, identifying a sequence of the data indicative of a first end of a first extended multiblock of the one or more extended multiblocks; and

identifying a user-selected number of ends of extended multiblocks in the one or more extended multiblocks.

6. The electronic device of claim 5 , wherein the user-selected number is one, two, or three.

7. The electronic device of claim 1 , wherein the second electronic device comprises a transmitter configured to send the data to the receiver.

8. The electronic device of claim 1 , wherein the electronic device comprises a programmable logic device.

9. The electronic device of claim 8 , wherein the programmable logic device comprises a field programmable gate array (FPGA).

10. A non-transitory computer readable medium comprising instructions that, when executed, are configured to cause a programmable logic device to:

receive data from an electronic device;

identify potential sync header locations within a portion of the data by performing a mutually exclusive or (XOR) logic operation on a plurality of sequential pairs of bits of the data; and

identify sync headers in the data by determining which of the potential sync header locations is shared in subsequent portions of the data.

11. The non-transitory computer readable medium of claim 10 , wherein the instructions, when executed, are configured to cause the programmable logic device to identify the sync headers by:

identifying the potential sync header locations in a first block of the data;

determining one or more second potential sync header locations in a second block of the data; and

determining which of the potential sync header locations and the one or more second potential locations occupy the same bit positions.

12. The non-transitory computer readable medium of claim 10 , wherein:

the data comprises a plurality of blocks; and

the instructions, when executed, are configured to cause the programmable logic device to identify the sync headers by identifying the potential sync header locations within each block of the plurality of blocks until only one common potential sync header location is identified in each of the plurality of blocks.

13. The non-transitory computer readable medium of claim 10 , wherein the instructions, when executed, are configured to cause the programmable logic device to determine the potential sync header locations by identifying one or more transitions between consecutive bits of the data.

14. The non-transitory computer readable medium of claim 10 , wherein the instructions, when executed, are configured to cause the programmable logic device to align the data by:

determining an end of a first extended multiblock of a plurality of extended multiblocks of the data; and

determining a user-selected number of ends of extended multiblocks of the plurality of extended multiblocks after determining the end of the first extended multiblock.

15. The non-transitory computer readable medium of claim 14 , wherein the instructions, wherein the user-selected number of ends is one, two, three, or four.

16. The non-transitory computer readable medium of claim 10 , wherein the programmable logic device comprises a field programmable logic device (FPGA) or application specific integrated circuit (ASIC).

17. A computer-implemented method of aligning data, comprising:

receiving, via an integrated circuit, data from an electronic device, wherein the data comprises one or more extended multiblocks, each of the one or more extended multiblocks comprises at least one multiblock, and the at least one multiblock comprises a plurality of blocks;

identifying potential sync header locations within a portion of the data by performing a mutually exclusive or (XOR) logic operation on a plurality of sequential pairs of bits of the data;

identifying sync headers in the data by determining which of the potential sync header locations is shared in subsequent portions of the data; and

identifying one or more ends of the one or more extended multiblocks.

18. The computer-implemented method of claim 17 , comprising:

applying a sync header lock after identifying the sync headers; and

identifying the one or more ends of the one or more extended multiblocks after applying the sync header lock.

19. The computer-implemented method of claim 18 , wherein identifying the one or more ends of the one or more extended multiblocks comprises:

identifying a first end of a first extended multiblock of the one or more extended multiblocks; and

identifying a user-selected number of the one or more ends of the one or more extended blocks of the data after the first extended multiblock.

20. The computer-implemented method of claim 19 , wherein:

the integrated circuit comprises a programmable logic device; and

the user-selected number is one, two, three, or four.
