Abstract

The present embodiments provide methods, systems and apparatuses that facilitate communication between two or more devices. Some of these methods identify a first communication to be transmitted and generate a first plurality of frames such that bit data of each of the frames of the first plurality of frames is different than the bit data of each of the other frames of the first plurality of frames, and that a first frame of the first plurality of frames include at least a first portion of the first communication. The first plurality of frames can then be transmitted.

Claims

1. A method of implementing serial communication, comprising:

identifying a first communication to be transmitted;

generating a first plurality of frames such that bit data of each of the frames of the first plurality of frames is different than the bit data of each of the other frames of the first plurality of frames, and that a first frame of the first plurality of frames comprises at least a first portion of the first communication; and

transmitting the first plurality of frames.

2. The method of claim 1, further comprising:

selecting a first sequence pattern;

determining a plurality of sequence numbers defining the first sequence pattern; and

wherein generating the first plurality of frames comprises incorporating one of the sequence numbers into each of the first plurality of frames.

3. The method of claim 2, wherein the determining the plurality of sequence numbers comprises determining the sequence numbers such that each of the plurality of sequence numbers is different.

4. The method of claim 1, wherein the generating the first plurality of frames comprises incorporating at least the first portion of the first communication into at least the first frame of the first plurality of frames and incorporating at least a second portion of the first communication into at least the second frame of the first plurality of frames.

5. The method of claim 4, further comprising:

generating a second plurality of frames such that at least a first frame of the second plurality of frames is identical to the first frame of the first plurality of frames and that a second frame of the second plurality of frames is identical to the second frame of the first plurality of frames; and

transmitting the second plurality of frames.

6. The method of claim 1, further comprising:

generating a second plurality of frames such that bit data of each of the frame of the second plurality of frames is different than the bit data of each of the other frames of the first plurality of frames, and that at least a first frame of the second plurality of frames is identical to the first frame of the first plurality of frames; and

transmitting the second plurality of frames.

7. The method of claim 1, further comprising:

determining whether to incorporate sequence numbers into the first plurality of frames;

implementing the generating the first plurality of frames comprising incorporating a sequence number into each of the frames of the first plurality of frames when it is determined that the sequence numbers are to be incorporated into the first plurality of frames.

8. The method of claim 1, wherein the determining whether to incorporate sequence numbers into the first plurality of frames comprises identifying a receiving device and determining whether the receiving device expects to receive frames with sequence numbers.

9. The method of claim 8, further comprising:

determining whether to duplicate the first frame of the first plurality of frames in a second plurality of frames when it is determined that sequence numbers are not to be incorporated into the first plurality of frames; and

generating the second plurality of frames such that bit data of each of the frame of the second plurality of frames is different than the bit data of each of the other frames of the second plurality of frames, and that a first frame of the second plurality of frames is a duplicate of the first frame of the first plurality of frames.

10. The method of claim 9, further comprising:

identifying a second communication to be transmitted;

determining whether a first frame of a third plurality of frames is to be duplicated in the third plurality of frames; and

generating the third plurality of frames such that the first frame is duplicated such that at least a second frame of the third plurality of frames is the duplicate of the first frame of the third plurality; and

transmitting the third plurality of frames.

11. The method of claim 10, further comprising:

identifying that the first communication is to be transmitted to a first receiving device; and

identifying that the second communication is to be transmitted to a second receiving device.

12. A method of serially communicating data, comprising:

receiving a first plurality of frames each comprising bit data;

determining whether the bit data of each of the first plurality of frames is different from the bit data of each of the other frames of the first plurality of frames;

extracting a portion of the bit data from each of the first plurality of frames when it is determined that the bit data of each of the first plurality of frames is different from the bit data of each of the other frames of the first plurality of frames;

arranging the portions of the bit data from each of the first plurality of frames;

determining whether the arranged portions of the bit data match a predefined arrangement of sequence numbers; and

extracting a first payload from first frame of the first plurality of frames when the arranged portions of the bit data match the predefined arrangement of sequence numbers.

13. The method of claim 12, wherein the extracting the portion of the bit data comprises extracting a sequence number from each of the first plurality of frames.

14. The method of claim 12, further comprising:

receiving a second plurality of frames each comprising bit data;

determining whether a first frame of the second plurality of frames is identical to the first frame of the first plurality of frames when it is determined that the arranged portions of the bit data do not match the predefined arrangement of sequence numbers; and

extracting the first payload from first frame of the first plurality of frames when the first frame of the first plurality of frames is identical to the first frame of the second plurality of frames.

15. The method of claim 14, further comprising:

determining whether a second frame of the first plurality of frames is identical to a second frame of the second plurality of frames;

extracting a second payload from the second frame of the first plurality of frames when the a second frame of the first plurality of data is identical to the second frame of the second plurality of frames; and

determining a communication comprising combining at least a portion of the first payload with at least a portion of the second payload.

16. The method of claim 14, further comprising:

extracting the first payload from the first frame of the first plurality of frames when it is determined that the bit data of each of the first plurality of frames is not different from the bit data of each of the other frames of the first plurality of frames and that the bit data of the first frame of the first plurality of frames is identical to the bit data of a second frame of the first plurality of data.

17. A method of serially communicating data, comprising:

receiving a first plurality of frames where each frame comprises bit data;

determining whether the bit data of each of the first plurality of frames is different from the bit data of each of the other frames of the first plurality of frames;

receiving a second plurality of frames where each frame comprises bit data;
