Abstract

A data processor and method of controlling the performance of a data processor are provided. The data processor includes a memory that is operable to store at least two of the application programs and that can be executed on the data processor. A performance module is operable to monitor a performance flag and output a stop command as a function of the presence of the performance flag, wherein the performance module generates a command that terminates at least one of the application programs as a function of the outputting of a stop command.

Claims

1. A method that is executable on a data processor including at least two running application programs, the method comprising:

monitoring a performance flag;

setting, by a first running application program of the at least two running application programs, the performance flag when the first running application program is entering a critical phase, the first running application program is a critical application program having a priority;

generating a stop command as a function of ascertaining the performance flag;

outputting the stop command;

ascertaining at least a second running application program of the at least two running programs, the second running application program having a priority that is lower than the priority of the first running application program;

terminating the ascertained second running application program in response to outputting the stop command prior to the second running application program becoming unresponsive and in order to prevent a full-capacity utilization of a central processing unit or a random access memory of the data processor, the first running application program not being terminated in response to outputting the stop command; and

deleting the performance flag based on detection of a termination of the first running application program or the first running application program exiting the critical phase.

2. The method as defined by claim 1, further including:

ascertaining the second running application program to be terminated as a function of the outputting of the stop command.

3. The method as defined by claim 2, further including:

outputting information identifying the first running application program, in conjunction with the setting of the performance flag by the first running application program.

4. The method as defined by claim 3, further including:

ascertaining the second running application program to be terminated as a function of the outputting of the stop command and of the information identifying the first running application program.

5. The method as defined by claim 4, further including:

entering one or more corresponding entries in a stop script as a function of ascertaining the second running application program to be terminated.

6. The method as defined by claim 5, further including:

executing the stop script; and

terminating the second running application program as a function of the one or more corresponding entries in the stop script.

7. The method as defined by claim 1, further including:

outputting a start command; and

starting at least one application program as a function of the outputting of the start command.

8. The method as defined by claim 7, wherein outputting the start command is a function of the deleting, and

wherein the deleting is a running application program of the at least two running application programs.

9. The method as defined by claim 8, further including:

ascertaining the at least one application program to be started as a function of the outputting of the start command.

10. The method as defined by claim 9, further including:

outputting information identifying the at least one application program to be started in conjunction with the deletion of the performance flag by the running application program.

11. The method as defined by claim 10, further including:

ascertaining the at least one application program to be started as a function of the outputting of the start command and as a function of the information identifying the at least one application program to be started.

12. The method as defined by claim 11, further including:

entering one or more corresponding entries in a start script as a function of ascertaining the at least one application program to be started.

13. The method as defined by claim 12, further including:

executing the start script; and

starting the at least one application program as a function of the one or more corresponding entries in the start script.

14. A data processor comprising:

a central processing unit;

a memory;

at least two application programs stored in the memory and executing on the data processor, a first application program of the at least two application programs being configured to set a performance flag when the first application program is entering a critical phase, the first application program is a critical application program having a priority; and

a performance module configured to monitor the performance flag and output a stop command as a function of the presence of the performance flag,

wherein the performance module is configured to ascertain at least a second application program of the at least two application programs, the second application program having a priority that is lower than the priority of the first application program, the performance module is further configured to generate a command that terminates the ascertained second application program as a function of the outputting of the stop command prior to the second running application program becoming unresponsive and in order to prevent a full-capacity utilization of the memory of the data processor, the first application program not being terminated as a function of the outputting of the stop command, and

wherein the first application program is configured to cause the performance flag to be deleted, such that the performance flag is deleted based on detection of a termination of the first application program or the first application program exiting the critical phase.

15. The data processor as defined by claim 14, wherein the performance module is configured to ascertain the second application program to be terminated as a function of the stop command that is output.

16. The data processor as defined by claim 15, further including a stop script, wherein the performance module is configured to enter one or more corresponding entries in the stop script as a function of ascertaining the second application program to be terminated.

17. The data processor as defined by claim 16, wherein the stop script is configured to terminate the second application program as a function of a corresponding entry in the stop script.

18. The data processor as defined by claim 17, wherein the performance module is configured to output a start command as a function of a deletion of the performance flag, and

wherein the performance module is configured to generate a command that starts an application program of the at least two application programs as a function of the outputting of the start command.

19. The data processor as defined by claim 18, wherein the performance module is configured to ascertain the application program to be started as a function of the outputting of the start command.

20. The data processor as defined by claim 19, further including a start script,

wherein the performance module is configured to enter one or more corresponding entries in the start script as a function of ascertaining the application program to be started.

21. The data processor as defined by claim 20, wherein the application program to be started is configured to be started as a function of a corresponding entry in the start script by execution of the start script.

22. A method that is executable on a data processor including at least two running application programs for radiological medical equipment, the method comprising:

monitoring a performance flag;

setting, by a first running application program of the at least two running application programs, the performance flag when the first running application program is entering a critical phase, wherein the first running application program is a critical application program having a priority, and the first running application program comprises controlling a patient scan;

generating a stop command as a function of ascertaining the performance flag;

outputting the stop command;

ascertaining at least a second running application program of the at least two running programs, the second running application program having a priority that is lower than the priority of the first running application program;

terminating the ascertained second running application program in response to outputting the stop command prior to and in order to prevent a full-capacity utilization of a central processing unit or a random access memory of the data processor, the first running application program not being terminated in response to outputting the stop command; and

deleting the performance flag based on detection of a termination of the first running application program or the first running application program exiting the critical phase.
