Abstract

A system and method for providing seamless communication with threads executing on an embedded computer. Using a DAT system, a programmer can test the communication interfaces of a thread via either a scripting program, any COM-compliant program, or a graphical test utility. The DAT system automatically formats a block of data that is transmitted between the embedded computer and a host computer and accounts for machine specific enumeration sizes, machine specific pointer sizes, machine specific structure alignment boundaries, machine specific integer sizes, and machine specific byte ordering.

Claims

1. A method comprising:

transmitting a request from a host device to a target device to intercept a call from an invoking routine to an invoked routine;

intercepting the call;

collecting at least one parameter that is provided as part of the call to the invoked routine;

transmitting the parameter from the target device to the host device; and

modifying the parameter based upon a characteristic of the host device and the target device.

2. The method of claim 1, additionally comprising modifying the invoking routine to call an interception routine.

3. The method of claim 1, additionally comprising:

renaming the invoked routine from a first name to a second name; and

providing an interception module having the first name.

4. The method of claim 1, additionally comprising:

transmitting return information from the host device to the target device;

modifying the return information based upon a characteristic of the host device and the target device; and

providing the transmitted return information to the invoking routine of the invoked routine.

5. The method of claim 4, additionally comprising:

from the host device, invoking the intercepted invoked routine on the target device; and

receiving return information from the invoked routine; and

wherein transmitting the return information includes providing the received return information from the invoked routine.

6. The method of claim 1, additionally comprising halting the interception of calls from the invoking routine to the invoked routine.

7. The method of claim 1, wherein the request from the host device to the target is received asynchronously with respect to the execution of the invoking routine.

8. The method of claim 1, additionally comprising storing the transmitted parameter in the host device.

9. A system comprising:

means for transmitting a request from a host device to a target device to intercept a call from an invoking routine to an invoked routine;

means for intercepting the call;

means for collecting at least one parameter that is provided as part of the call to the invoked routine;

means for transmitting the parameter from the target device to the host device; and

means for modifying the parameter based upon a characteristic of the host device and the target device.

10. The system of claim 9, additionally comprising:

means for transmitting return information from the host device to the target device;

means for modifying the return information based upon a characteristic of the host device and the target device; and

means for providing the transmitted return information to the invoking routine of the invoked routine.

11. The system of claim 9, wherein the request from the host device to the target is received asynchronously with respect to the execution of the invoking routine.

12. The system of claim 9, additionally means for comprising means for storing the transmitted parameter in the host device.

13. The system of claim 9, additionally comprising means for modifying the invoking routine to call an interception routine.

14. The system of claim 9, additionally comprising:

renaming the invoked routine from a first name to a second name; and

providing an interception module having the first name.

18. The system of claim 13, additionally comprising storing the transmitted parameter in the host device.

15. A system comprising:

a target device; and

a host device configured to transmit to the target device a request to intercept an call from an invoking routine to an invoked routine, the target device configured to intercept the call and collect at least one parameter that parameter that is provided as part of the call, the target device configured to transmit the parameter from the target device to the host device; and

the target device configured to modify the parameter based upon a characteristic of the host device and the target device.

16. The system of claim 15, wherein the host device is configured to modify return information based upon a characteristic of the host device and the target device, wherein the host device is configured to transmit the modified return information to the target device, and wherein the target device provides the transmitted return information to the invoking routine of the invoked routine.

17. The method of claim 15, wherein the request from the host device to the target is received asynchronously with respect to the execution of the invoking routine.

19. A method of generating code in an electronic device, the method comprising:

in the electronic device, identifying at least routine to be intercepted; and

in the electronic device, generating interception code, wherein the interception code is configured to during execution and in response to a signal from a requester invoke a routine to transmit at least one parameter that is associated with the intercepted routine to the requester.

20. The method of claim 19, additionally comprising providing a routine to modify the parameters based upon a characteristic of the host device and the target device.

21. The method of claim 19, additionally comprising modifying an invoking routine to call an interception routine.

22. The method of claim 19, additionally comprising:

renaming the invoked routine from a first name to a second name; and

providing an interception module having the first name.
