Developed and delivered a power-efficient thread sleep management feature for the UCSD-E4E/smartfin-fw3 repository, focusing on optimizing embedded system performance. The work introduced sleep logic to manage thread behavior during idle periods, effectively reducing CPU power consumption without compromising system responsiveness. Using C++ and YAML, the implementation aligned with CI/CD practices and leveraged GitHub Actions for streamlined version control and deployment. All code changes were thoroughly documented and linked to the relevant commit, establishing a solid foundation for future power-saving enhancements. This contribution improved energy efficiency for edge devices and demonstrated disciplined, performance-oriented embedded systems development within a collaborative workflow.
