Abstract

A method of processing J1850 requests using a scan tool having multiple processor systems is provided. The scan tool includes a first processor that processes data according to scan tool functions to assist with diagnosing and repairing a vehicle. A second processor receives data transmitted to the first processor and stores the data in a buffer. The second processor determines whether the data is complete to enable the first processor to make a determination regarding the data.

Claims

1. A method of data processing in a scan tool, comprising:

receiving data at a first processor;

storing the data in a buffer;

transmitting the data from the buffer to the first processor;

transmitting the data to a second processor; and

determining whether the data should be processed by the first processor.

2. The method of claim 1, further comprising transmitting an interrupt from the first processor to the second processor.

3. The method of claim 1 further comprising determining whether the data is complete.

4. The method of claim 1, further comprising applying at least one filter to the data.

5. The method of claim 1, further comprising transmitting an interrupt from the second processor to the first processor.

6. The method of claim 1, further comprising performing bus arbitration.

7. The method of claim 6, wherein the second processor performs the bus arbitration.

8. The method of claim 6, further comprising performing automatic re-tries on a loss of bus priority.

9. A method of data processing in a scan tool, comprising:

receiving data at a first processor;

storing the data in a buffer;

determining whether the data is complete;

transmitting the data to a second processor;

determining whether the data should be processed by the first processor; and

transmitting an interrupt from the first processor to the second processor.

10. The method of claim 9, further comprising transmitting the data from the buffer to the first processor.

11. The method of claim 9, further comprising applying at least one filter to the data.

12. The method of claim 9, further comprising transmitting an interrupt from the second processor to the first processor.

13. A method of data processing in a scan tool, comprising:

receiving data at a first processor;

transmitting an interrupt from the first processor to a second processor;

storing the data in a buffer;

determining whether the data is complete;

transmitting the data to the second processor; and

determining whether the data should be processed by the first processor or by the second processor.

14. The method of claim 13, further comprising performing bus arbitration.

15. The method of claim 14, wherein the second processor performs the bus arbitration.

16. The method of claim 14, further comprising performing automatic re-tries on a loss of bus priority.

17. The method of claim 13, further comprising applying at least one filter to the data.
