Abstract

Software that modifies the source code for readily available software tasks—typically applications and hardware drivers—so that a small, fast, reliable operating system can be synthesized to control execution of these readily available software tasks.

Claims

1. ) A method for customizing task source code, typically hardware drivers and applications, for use with a synthesized operating system, comprising:

a) searching said source code for operating system application programming interfaces (APIs); and

b) substituting in said source code instructions, including synthesis primitives, for said APIs.

2. ) The method of claim 1), further comprising synthesizing said task source code with said substituted source code.

3. ) The method of claim 2), further comprising synthesizing an operating system.

4. ) The method of claim 3), further comprising compiling said task source code and operating system source code.

5. ) The method of claim 1) wherein said APIs include thread manipulation APIs.

6. ) The method of claim 1) wherein said APIs include functions for achieving shared access to system resources.

7. ) A method for customizing task source code, typically hardware drivers and applications, for use with a synthesized operating system, comprising:

a) searching said source code for operating system application programming interfaces (APIs); and

b) substituting in said source code instructions, including synthesis primitives, for said APIs; and

c) modifying a synthesis configuration file.

8. ) The method of claim 7), further comprising synthesizing said task source code with said substituted source code.

9. ) The method of claim 8), further comprising synthesizing an operating system.

10. ) The method of claim 9), further comprising compiling said task source code and operating system source code.

11. ) The method of claim 7) wherein said APIs include thread manipulation APIs.

12. ) The method of claim 7) wherein said APIs include functions for achieving shared access to system resources.

13. ) An apparatus including a software program for modifying task source code, typically hardware drivers and applications, for use on a synthesized operating system, comprising:

a) means for searching with said source code for operating system application programming interfaces (APIs); and

b) means for substituting in said source code instructions, including synthesis primitives, for said APIs.

14. ) The apparatus of claim 13), further comprising means for synthesizing said task source code with said substituted source code.

15. ) The apparatus of claim 14), further comprising means for synthesizing an operating system.

16. ) The method of claim 15), further comprising compiling said task source code and operating system source code.

17. ) The apparatus of claim 13) wherein said APIs include thread manipulation APIs.

18. ) The apparatus of claim 13) wherein said APIs include functions for achieving shared access to system resources.

19. ) An apparatus including a software program for modifying task source code, typically hardware drivers and applications, for use on a synthesized operating system, comprising:

a) means for searching with said source code for operating system application programming interfaces (APIs); and

b) means for substituting in said source code instructions, including synthesis primitives, for said APIs; and

c) means for modifying a synthesis configuration file.

20. ) The apparatus of claim 19), further comprising means for synthesizing said task source code with said substituted source code.

21. ) The apparatus of claim 20), further comprising means for synthesizing an operating system.

22. ) The method of claim 21), further comprising compiling said task source code and operating system source code.

23. ) The apparatus of claim 19) wherein said APIs include thread manipulation APIs.

24. ) The apparatus of claim 19) wherein said APIs include functions for achieving shared access to system resources.
