Angela Cheng developed a temperature monitoring feature for the Marvell HSM OCTEON SoC within the facebook/OpenBIC repository. She implemented sensor read and configuration APIs in C, integrating them into the existing embedded sensor management framework to provide real-time SoC temperature visibility. Her work included designing new logic for sensor configuration and reading, validated through hardware power-cycle tests to ensure stable and accurate results. By enabling proactive thermal management, Angela’s contribution addressed the risk of system throttling or downtime. The changes improved platform reliability and maintainability, demonstrating her skills in C programming, embedded systems, and sensor integration within production hardware.
