Abstract

A method of implementing program updates in an electronic system includes requesting the system to accept a program update and loading replacement programs for execution. The method includes using an operating system to determine when programs running on an electronic system have finished an execution cycle and then commencing the replacement process.

Claims

1. A method of implementing program updates for at least one program executing within an electronic system during substantial continued system execution, said method comprising the steps of:

requesting the electronic system to accept an update of at least one of multiple programs executing within the electronic system for multiple times without ceasing execution of the multiple programs;

determining if at least one of the multiple programs requested to be updated is executing when the electronic system is requested to accept an update of each of the multiple programs to be updated; and

loading at least one replacement program to fulfill the request to accept an update of each of the multiple programs to be updated.

2. A method in accordance with claim 1 wherein said step of requesting the electronic system to accept an update of at least one of multiple programs comprises the step of requesting the electronic system to perform a Run Mode Store of each of the multiple programs to be updated.

3. A method in accordance with claim 2 wherein said step of requesting the electronic system to perform a Run Mode Store of each of the multiple programs to be updated comprises the step of requesting the electronic system to delete a program.

4. A method in accordance with claim 2 wherein said step of requesting the electronic system to perform a Run Mode Store of each of the multiple programs to be updated comprises the step of requesting the electronic system to add a program.

5. A method in accordance with claim 2 wherein said step of requesting the electronic system to perform a Run Mode Store of each of the multiple programs to be updated comprises the step of requesting the electronic system to swap one program for another.

6. A method in accordance with claim 1 wherein said step of loading at least one replacement program comprises the step of waiting for a time when all programs within the system are not executing.

7. A method in accordance with claim 1 wherein said step of loading at least one replacement program comprises the step of waiting for a time when all programs slated for updating within the electronic system are not executing.

8. A method in accordance with claim 1 wherein said step of loading at least one replacement program comprises the step of waiting for each program slated for updating within the electronic system to finish executing.

9. A method in accordance with claim 1 wherein said step of requesting the electronic system to accept an update of at least one of multiple programs comprises the step of maintaining a list of programs that are currently executing.

10. A method in accordance with claim 1 wherein said step of requesting the system to accept an update of at least one of multiple programs comprises the step of flagging programs that are currently executing for later processing.

11. A method in accordance with claim 1 wherein said loading at least one replacement program comprises loading the at least one replacement program during a repetition of execution of remaining of the multiple programs.

12. A method in accordance with claim 1 wherein said loading at least one replacement program comprises loading the at least one replacement program during a continuous repetition of execution of remaining of the multiple programs.

13. A method in accordance with claim 1 wherein said loading at least one replacement program comprises performing one of an addition and a deletion operation on each of the multiple programs to be updated.

14. An electronic system comprising a controller, said electronic system including a memory, a backplane, and a plurality of modules connected to the controller via said backplane, an operating system, and multiple program blocks configured to execute multiple times, said controller configured to receive a request to update at least one of the multiple program blocks without ceasing execution of the multiple program blocks executing within the electronic system, said controller configured to store within said memory a control program configured to operate in a microcycle mode for updating at least one of the multiple program blocks on receiving the request, said control program configured to determine if at least one of the multiple prop-ram blocks is executing when the request is received.

15. An electronic system according to claim 14 wherein said controller is further configured to request the electronic system to accept a program update and load at least one replacement program for execution.

16. An electronic system according to claim 14 wherein said controller is further configured to request the electronic system to perform a Run Mode Store of each of the multiple program blocks to be updated.

17. An electronic system according to claim 16 wherein said controller is further configured to request the electronic system to delete a program.

18. An electronic system according to claim 16 wherein said controller is further configured to request the electronic system to add a program.

19. An electronic system according to claim 16 wherein said controller is further configured to request the electronic system to swap one program for another.

20. An electronic system according to claim 14 wherein said controller is further configured to wait for a time when all programs within the system are not executing.

21. An electronic system according to claim 14 wherein said controller is further configured to wait for a time when all programs slated for updating within the electronic system are not executing.

22. An electronic system according to claim 14 wherein said controller is further configured to wait for each program slated for updating within the electronic system to finish executing.

23. An electronic system according to claim 14 wherein said controller is further configured to maintain a list of programs currently executing.

24. An electronic system according to claim 14 wherein said controller is further configured to flag programs currently executing for later processing.

25. An electronic system according to claim 14 wherein said controller is configured to load at least one replacement program block to fulfill the request, and said controller is configured to load the least one replacement program block during a repetition of execution of remaining of the multiple program blocks.

26. An electronic system according to claim 14 wherein said controller is configured to load at least one replacement program block to fulfill the request, and said controller is configured to load the least one replacement program block during a continuous repetition of execution of remaining of the multiple program blocks.

27. An electronic system according to claim 14 wherein said controller is configured to perform one of an addition and a deletion operation on each of the multiple program blocks to be updated to fulfill the request.
