Abstract
Debugging and/or modifying of ROM-based embedded software systems is realized by advantageously employing an extensible interpreter and inserting requests for 'Customizable Call-Outs' (CCOs) throughout the ROM-based embedded software. Then, the ROM-based embedded software system can easily be directly enhanced, i.e., extended, at run time to provide virtually limitless new functionality. Advantages of the invention are that the ROM-based embedded system software does not need to be rebuilt or reloaded, and the functionality of the debugging/modifying software is decided at the time of detecting a problem and/or of providing a modification, not before. By employing the extensible interpreter, the extension to the ROM-based embedded software is implemented, i.e., written and loaded, in the system directly, without the need for or use of an additional external computer platform or compiler.
