Abstract

Some embodiments provide a system that executes a web application. During operation, the system loads the web application in a web browser and loads a native code module associated with the web application into a secure runtime environment. Next, the system provides input data associated with the web application to the native code module and processes the input data using the native code module to obtain output data. Finally, the system provides the output data to the web application for use by the web application.

Claims

1. A method for executing a web application, comprising:

loading the web application in a web browser;

loading a native code module associated with the web application into a secure runtime environment;

providing input data associated with the web application to the native code module;

processing the input data using the native code module to obtain output data; and

providing the output data to the web application for use by the web application.

2. The method of claim 1, further comprising:

validating the native code module prior to loading the native code module into the secure runtime environment.

3. The method of claim 1, wherein the output data is provided to a trusted plugin associated with the web browser for use by the trusted plugin.

4. The method of claim 3, wherein the output data is used by the trusted plugin to render graphics for the web application.

5. The method of claim 1, wherein the native code module provides at least one of simulation, signal processing, artificial intelligence, modeling, and analysis for the web application.

6. The method of claim 1, wherein the secure runtime environment is implemented by a plugin associated with the web browser.

7. The method of claim 1, wherein the web application and the native code module are platform independent.

8. The method of claim 1,

wherein the input data is provided to the native code module using a first inter-module communication (IMC) buffer, and

wherein the output data is provided to the web application using a second IMC buffer.

9. The method of claim 1, wherein processing the input data involves performing a series of mathematical calculations using the input data.

10. A system for executing a web application, comprising:

a web browser configured to load the web application;

a native code module associated with the web application; and

a secure runtime environment configured to execute the native code module,

wherein the native code module is configured to;

obtain input data associated with the web application;

process the input data to obtain output data; and

provide the output data to the web application for use by the web application.

11. The system of claim 10, further comprising:

a validator configured to validate the native code module prior executing the native code module.

12. The system of claim 11, wherein the secure runtime environment and the validator are implemented using a plugin associated with the web browser.

13. The system of claim 10, further comprising:

a trusted plugin associated with the web browser,

wherein the output data is provided to the trusted plugin for use by the trusted plugin.

14. The system of claim 13, wherein the output data is used by the trusted plugin to render graphics for the web application.

15. The system of claim 10, further comprising:

a first inter-module communication (IMC) buffer configured to provide the input data to the native code module; and

a second IMC buffer configured to provide the output data to the web application.

16. The system of claim 10, wherein the native code module provides at least one of simulation, signal processing, artificial intelligence, modeling, and analysis for the web application.

17. The system of claim 10, wherein the web application and the native code module are platform independent.

18. The system of claim 10, wherein processing the input data involves performing a series of mathematical calculations using the input data.

19. A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for executing a web application, the method comprising:

loading the web application in a web browser;

loading a native code module associated with the web application into a secure runtime environment;

providing input data associated with the web application to the native code module;

processing the input data using the native code module to obtain output data; and

providing the output data to the web application for use by the web application.

20. The computer-readable storage medium of claim 19, the method further comprising:

validating the native code module prior to loading the native code module into the secure runtime environment.

21. The computer-readable storage medium of claim 19, wherein the output data is provided to a trusted plugin associated with the web browser for use by the trusted plugin.

22. The computer-readable storage medium of claim 21, wherein the output data is used by the trusted plugin to render graphics for the web application.

23. The computer-readable storage medium of claim 19, wherein the native code module provides at least one of simulation, signal processing, artificial intelligence, modeling, and analysis for the web application.

24. The computer-readable storage medium of claim 19, wherein the secure runtime environment is implemented by a plugin associated with the web browser.

25. The computer-readable storage medium of claim 19, wherein the web application and the native code module are platform independent.

26. The computer-readable storage medium of claim 19,

wherein the input data is provided to the native code module using a first inter-module communication (IMC) buffer, and

wherein the output data is provided to the web application using a second IMC buffer.

27. The computer-readable storage medium of claim 19, wherein processing the input data involves performing a series of mathematical calculations using the input data.
