Power management implementation in FreeRTOS on LM3S3748

Abstract

Power consumption has become a major concern of embedded systems today. With the aim to reduce power consumption during the runtime, operating systems are dealing with power management. In this work, the FreeRTOS port is extended with power management features on LM3S3748 microcontroller. Tickless idle technique is implemented to provide more powersaving during the processor idle periods.
