Though exception handling is crucial for enhancing the reliability of embedded systems, the traditional exception handling methods for hardware are difficult to adapt the development of embedded systems. In this paper, the exception handling require- ments of embedded systems was analyzed, and a structural exception handling framework was proposed, in which some new features were introduced. Then taking the ease of CGEL, the concrete realization and applying of this exception handling framework for embed- ded system was described. Comparison results with other exception handling methods show that the exception handling framework has perfect functions and rich interface, a
