RISC architecture is extensively preferred for the development of high end embedded application in increasing demand like mobile phones with space and power constraints. This has led to development of ARM processors with higher code density than previously achievable. Modeling of a processor core facilitates feature development based on the current architecture implementation to further reduced memory power and chip size requirements. An attempt is made in this paper to provide an industry standard model of the ARM Cortex-M3 Processor core recent in the series of processors widely used for embedded system development.
