In charge of the System-on-Chip (SoC) level power/system management features including but not limited to power prediction/managemnt, Dynamic Voltage and Frequency Scaling (DVFS), Reliability, Availability, Serviceability (RAS) features as well as out-of-band controls. Being engaged in the entire SoC development phases and provide the end-to-end support across pre-silicon emulation, post-silicon calibration, bug-fix till delivering to customers. Your responsibility will include:
Design, implement and validate firmware in C, assembly for the embedded Xtensa LX Power Management (PM) sub-system of CIX SoC
Develop and maintain the RTOS infrastructure running on the PM sub-system.
Develop peripheral drivers (SPI/Ethernet/I2C/PWM…) for the PM sub-system
Develop scripts on host PC to speed up firmware development/validation work.
Being engaged in manufacturing, algorithm parameters tuning and sensor calibrations.
Work with system designers to extract low-power requirements and implement theirs algorithms.
Work closely with OS/SW team to implement the interface/service docking with upper softwares.
Work closely with test engineer to fix the defects on time.
Perform code reviews, write and maintain relevant documents
