Abstract

A method of transferring at least two data streams in a medical device is provided. First data stream data is collected into a first intermediate register. Additional data stream data is collected into an additional intermediate register. First intermediate register contents are stored in at least one first output register. Systems and devices for using the method are also provided.

2. The method of claim 1, further comprising:

storing additional intermediate register contents in the first output register.

3. The method of claim 1 further comprising:

storing additional intermediate register contents in at least one additional output register.

4. The method of claim 3 further comprising:

7. The method of claim 1 further comprising:

transferring contents of the first output register to memory.

8. The method of claim 7 further comprising:

transferring contents of an additional output register to memory.

9. The method of claim 1 further comprising:

receiving compressed first data stream data.

10. The method of claim 1 further comprising:

receiving compressed additional data stream data.

11. The method of claim 1 further comprising:

collecting first data stream data until the first intermediate register is full.

12. The method of claim 1 further comprising:

collecting additional data stream data until the additional intermediate register is full.

13. The method of claim 1 further comprising:

storing remaining first intermediate register contents in the first intermediate register if the first output register is full.

14. The method of claim 1 further comprising:

storing remaining additional intermediate register contents in the additional intermediate register if the first output register is full.

15. A method of transferring at least two data streams in a medical device, comprising:

collecting first data stream data into a first intermediate register;

collecting additional data stream data into at least one additional intermediate register;

storing first intermediate register contents in a first output register; and

storing first intermediate register contents in the first output register if the state of the first output register is empty, when the first intermediate register is full.

16. The method of claim 15 further comprising:

storing first intermediate register contents in the additional output register if the state of the first output register is full.

17. The method of claim 15 wherein the additional intermediate register is full, further comprising:

storing additional intermediate register contents in the first output register if the state of the first output register is empty.

18. The method of claim 17 further comprising:

storing additional intermediate register contents in the additional output register if the state of the first output register is full.

19. A system for transferring at leant two data streams in a medical device, comprising:

means for collecting first data stream data into a first intermediate register;

means for collecting additional data stream data into at least one additional intermediate register;

means for storing first intermediate register contents in a first output register;

means for storing first intermediate register in at least one additional output register; and

means for storing remaining first intermediate register contents in the first intermediate register if the additional output register is full.

20. The system of claim 19, further comprising:

means for storing additional intermediate register contents in the first output register.

21. The system of claim 19, further comprising:

means for storing first intermediate register contents with an identification code that uniquely identifies the first data stream data.

22. The system of claim 19, further comprising:

means for storing additional intermediate register contents with an identification code that uniquely identifies the additional data stream data.

23. The system of claim 19, further comprising:

means for transferring contents of the first output register to memory.

24. The system of claim 23, further comprising:

means for transferring contents of an additional output register to memory.

25. The system of claim 19, further comprising:

means for collecting first data stream data until the first intermediate register is full.

26. The system of claim 19, further comprising:

means for collecting additional data stream date until the additional intermediate register is full.

27. The system of claim 19, further comprising:
