Modular Design Implementation in the Firmware of Complex Micro-Controller Based Products

In embedded systems, firmware serves an indispensable purpose. It enables system configuration and security, as well as performance optimization and system maintenance. Without firmware, embedded systems could not effectively function. Firmware code can be written in a variety of methods; however, it is crucial that the firmware be written efficiently and in accordance with the system's requirements. Due to the fact that the existing approach did not account for the possibility of cases involving the incorporation of modifications, redesigning is required. The redesign of the firmware increases the development time. Similarly, complex micro-controller based products' firmware requires a modular design. The absence of a modular design in code can result in a less efficient development process, a more difficult-to-maintain codebase, and a greater error and bug risk. In the proposed approach, the objective is to implement modular design in the firmware of complex micro-controller based products. Modular design facilitates modifications to be implemented without redesigning the entire firmware. Multiple functionalities are accommodated, thereby expanding the scopeof potential customers. Transitioning to the modular approach also results in the reduction in code size. The modular approach is therefore responsible for the firmware's reusability, readability.maintainability, and scalability.
