Alarm offset optimization apparatus of AUTOSAR operating system

1. An apparatus of optimizing an alarm offset for an AUTomotive Open System Architecture (AUTOSAR) operating system, the apparatus comprising:

a processor configured to input an offset value of a predetermined offset table to an offset variable value for each alarm information related to an alarm setting test file; and

the processor configured to execute the alarm setting test file based on the input offset value and to output an execution result for optimizing the alarm offset,

wherein the execution result includes a minimum CPU load, a maximum CPU load, and a number of times of a call of ErrorHook.

2. The apparatus of claim 1 , wherein the offset table includes a plurality of alarm information including a number of alarms, an alarm name, and an alarm period, and index information connected with each alarm information through an offset value.

3. The apparatus of claim 2 , wherein the start module is configured to input the offset value according to the index information as the offset variable value.

4. The apparatus of claim 2 , wherein the execution module is configured to execute the alarm setting test file in an order of the index information.

5. The apparatus of claim 1 , further including:

an offset table storing unit which is configured to store the offset table.

6. The apparatus of claim 4 , further including:

a load measuring module which is configured to measure a CPU load according to an execution of the alarm setting test file.

7. The apparatus of claim 4 , further including:

a reset module which requests a reset from the execution module so that the alarm setting test file is executed according to another index information when the execution of the alarm setting test file according to the index information is completed.

8. The apparatus of claim 4 , wherein when the execution of the alarm setting test file according to last index information is completed, the execution module is configured to transmit an execution result to an outside thereof by a pre-prepared communication method.

9. The apparatus of claim 1 , wherein the execution module is configured to compare the minimum CPU load, the maximum CPU load, and the number of times of the call of the ErrorHook with predetermined reference values and is configured to determine whether the minimum CPU load, the maximum CPU load, and the number of times of the call of the ErrorHook satisfies the predetermined reference values.

10. The apparatus of claim 1 , further including:

a producing tool which is configured to receive an input of alarm information connected with a task of the AUTOSAR operating system and produces an alarm setting file by use of the alarm information.

11. The apparatus of claim 10 , further including:

a correcting unit which is configured to correct an offset value of the alarm setting file to an offset variable value and generates the alarm setting test file.

12. A method of optimizing an alarm offset for an AUTomotive Open System Architecture (AUTOSAR) operating system, the method comprising:

inputting an offset value of a predetermined offset table to an offset variable value for each alarm information related to an alarm setting test file; and

executing the alarm setting test file based on the input offset value and outputting an execution result for optimizing the alarm offset; and

measuring a CPU load according to an execution of the alarm setting test file.

13. The method of claim 12 , wherein the offset table includes a plurality of alarm information including a number of alarms, an alarm name, and an alarm period, and index information connected with each alarm information through an offset value.

14. The method of claim 13 , wherein the offset value is input according to the index information as the offset variable value.

15. The method of claim 13 , wherein the alarm setting test file is executed in an order of the index information.

16. The method of claim 13 , further including:

executing the alarm setting test file according to another index information when the execution of the alarm setting test file according to the index information is completed.

17. The method of claim 12 ,

wherein the execution result includes a minimum CPU load, a maximum CPU load, and a number of times of a call of ErrorHook, and

wherein the method further includes:

comparing the minimum CPU load, the maximum CPU load, and the number of times of the call of the ErrorHook with predetermined reference values; and

determining whether the minimum CPU load, the maximum CPU load, and the number of times of the call of the ErrorHook satisfies the predetermined reference values.

18. The method of claim 17 , further including: resetting the execution of the alarm setting test file until the minimum CPU load, the maximum CPU load, and the number of times of the call of the ErrorHook for the alarm information according to a last index of the offset table are determined.
