Abstract

A host includes a controller configured to receive a request external to the host, wherein the request is for diagnostic information associated with central processing unit (CPU) for an application. The controller is further configured to collect the requested diagnostic information.

Claims

1. A host comprising:

a host controller configured to receive a request external to the host, wherein the request is for diagnostic information associated with central processing unit (CPU) for an application; and

the host controller further configured to collect the requested diagnostic information.

2. The host of claim 1, wherein the host controller is configured to receive the external request through a communication interface.

3. The host of claim 2, wherein the communication interface includes a cablecard.

4. The host of claim 3, wherein the host is configured to communicate with the cablecard using Generic Diagnostic Protocol.

5. The host of claim 1, wherein the requested diagnostic information contains information indicating capability of the CPU for driving the application.

6. The host of claim 5, wherein the information indicating the capability of the CPU contains information about a program execution time.

7. The host of claim 6, wherein the information indicating the program execution time uses a result of a time for executing a benchmarking program which is previously included in the host.

8. The host of claim 7, wherein the benchmarking program is obtained by downloading an benchmark application for measuring the program execution time from an external source which makes a request for the diagnostic information or implementing a benchmarking sample code provided by the external source.

9. The host of claim 5, wherein the information indicating the capability of the CPU contains information about a clock speed of the CUP.

10. The host of claim 5, wherein the information indicating the capability of the CPU contains information about the size of a D-cache of the CPU.

11. The host of claim 5, wherein the information indicating the capability of the CPU contains information about the size of an instruction cache of the CPU.

12. The host of claim 5, wherein the information indicating the capability of the CPU contains information about million instructions per second (MIPS) of the CPU.

13. The host of claim 5, wherein the information indicating the capability of the CPU contains first information about a program execution time, second information about a clock speed, third information about the size of a D-cache, fourth information about the size of an instruction cache, and fifth information about MIPS of the CPU.

14. The host of claim 6, wherein the information indicating the capability of the CPU further contains at least one of first information about a clock speed, second information about the size of a D-cache, third information about the size of an instruction cache, and fourth information about MIPS of the CPU.

15. The host of claim 1, wherein the application includes an Open Cable Application Platform (OCAP) application.

16. A communication device configured to communicate with a host, the communication device comprising:

a controller configured to receive a request external to the communication device, wherein the request is for diagnostic information associated with central processing unit (CPU) for an application;

the controller further configured to request the diagnostic information from the host using set value.

17. The communication device of claim 16, wherein the controller is configured to receive the requested diagnostic information from the host and the communication device is further configured to parse the requested diagnostic information in accordance with a predetermined protocol.

18. The communication device of claim 16, wherein the controller is configured to forward the parsed diagnostic information to a source requesting the diagnostic information.

19. The communication of claim 16, wherein the application includes an Open Cable Application Platform (OCAP) application.

20. A method comprising the steps of:

receiving a request external to a host, wherein the request is for diagnostic information associated with central processing unit (CPU) for an application;

collecting the requested diagnostic information in accordance with the request; and

forwarding the collected diagnostic information.

21. The method of claim 20 further comprising the step of receiving a version of the application at the host appropriate to the CPU for the application.

22. The method of claim 20 further comprising the steps of:

parsing the request for a value; and

determining, based on the value, whether the request is for the diagnostic information associated with the CPU for an application.

23. A method comprising the steps of:

requesting diagnostic information associated with central processing unit (CPU) for an application;

receiving the diagnostic information in accordance with the request; and

performing at least one of forwarding the diagnostic information and causing the diagnostic information to be displayed.

25. The method of claim 23 further comprising the step of forwarding the parsed diagnostic information to a source requesting the diagnostic information.

26. The method of claim 23 further comprising the step of collecting the requested diagnostic information.

27. The method of claim 23 further comprising the step of receiving a version the application appropriate to the CPU for the application.

24. The method of 23 further comprising the step of parsing the requested diagnostic information in accordance with a predetermined protocol.

28. A data structure comprising:

information defining a capability of central processing unit (CPU) for an application.

29. The data structure of claim 28, wherein the information defining the capability of the CPU contains first information about a program execution time.

30. The data structure of claim 29, wherein the information defining the capability of the CPU further contains at least one of the second information about a clock speed, third information about the size of D-cache, fourth information about the size of an I-cache, and fifth information about million instructions per second (MIPS) of the CPU.
