Abstract

An embedded system post-linker optimization automation method can include connecting to a network file system, coordinating a first handshaking procedure to initiate an embedded application from the network file system, coordinating a second handshaking procedure to initiate a training phase of the embedded application and coordinating a third handshaking procedure to initiate generation of an optimized embedded application from the embedded application during an optimization phase.

Claims

1. An embedded system post-linker optimization automation method, comprising:

connecting, via a computer, to a network file system;

coordinating a first handshaking procedure to initiate an embedded application from the network file system;

coordinating a second handshaking procedure to initiate a training phase of the embedded application; and

coordinating a third handshaking procedure to initiate generation of an optimized embedded application from the embedded application during an optimization phase.

2. The method as claimed in claim 1 wherein the first handshaking procedure includes generating an Embedded Application Started (EASTRT) file semaphore in the network file system, the EASTRT file semaphore indicating that the embedded application has started.

3. The method as claimed in claim 1 further comprising copying a profile data file to the network file system.

4. The method as claimed in claim 3 further comprising populating the profile data file with statistical data from the training phase.

5. The method as claimed in claim 1 wherein the second handshaking procedure includes waiting for a Training Phase Done (TPDN) file semaphore indicating that the training phase of the embedded application is complete.

6. The method as claimed in claim 1 wherein the third handshaking procedure includes receiving an Output Ready (ORDY) file semaphore indicating that an optimized embedded application has been generated.

7. The method as claimed in claim 1 further comprising copying the optimized embedded application to the network file system.

8. A computer program product including a non-transitory computer readable medium storing instructions for causing a computer to implement an embedded system post-linker optimization automation method, the method comprising:

connecting to a network file system;

coordinating a first handshaking procedure to initiate an embedded application from the network file system;

coordinating a second handshaking procedure to initiate a training phase of the embedded application; and

coordinating a third handshaking procedure to initiate generation of an optimized embedded application from the embedded application during an optimization phase.

9. The computer program product as claimed in claim 8 wherein the first handshaking procedure includes generating an Embedded Application Started (EASTRT) file semaphore in the network file system, the EASTRT file semaphore indicating that the embedded application has started.

10. The computer program product as claimed in claim 8 wherein the method further comprises copying a profile data file to the network file system.

11. The computer program product as claimed in claim 10 wherein the method further comprises populating the profile data file with statistical data from the training phase

12. The computer program product as claimed in claim 8 wherein the second handshaking procedure includes waiting for a Training Phase Done (TPDN) file semaphore indicating that the training phase of the embedded application is complete.

13. The computer program product as claimed in claim 8 wherein the third handshaking procedure includes receiving an Output Ready (ORDY) file semaphore indicating that an optimized embedded application has been generated.

14. The computer program product as claimed in claim 8 wherein the method further comprises copying the optimized embedded application to the network file system.

15. An embedded computer system, comprising:

a session command connection;

a network file system connection; and

a processor configured to start an embedded application in response to a session command received on the session command connection,

wherein the network file system connection is configured to coordinate handshaking file semaphores to automate an embedded system post-linker optimization automation procedure.

16. The system as claimed in claim 15 wherein the embedded system post-linker optimization automation procedure includes:

connecting to a network file system;

copying a profile data file to the network file system;

coordinating a first handshaking procedure to initiate the embedded application from the network file system;

coordinating a second handshaking procedure to initiate a training phase of the embedded application;

coordinating a third handshaking procedure to initiate generation of an optimized embedded application from the embedded application during an optimization phase.

17. The system as claimed in claim 16 wherein the first handshaking procedure includes generating an Embedded Application Started (EASTRT) file semaphore in the network file system, the EASTRT file semaphore indicating that the embedded application has started.

18. The system as claimed in claim 16 wherein the second handshaking procedure includes waiting for a Training Phase Done (TPDN) file semaphore indicating that the training phase of the embedded application is complete.

19. The system as claimed in claim 16 wherein the embedded system post-linker optimization automation procedure further comprises populating the profile data file with statistical data from the training phase.

20. The system as claimed in claim 16 wherein the third handshaking procedure includes receiving an Output Ready (ORDY) file semaphore indicating that an optimized embedded application has been generated, wherein the optimized embedded application is copied to the network file system.
