A Review on RTOS in Embedded Systems
Keywords:
ARM, Effective synchronization, Pragmatic approaches, Real-time traffic, RTOS, SoCsAbstract
Embedded systems have come to depend more and more on Real-Time Operating Systems (RTOS) due to the strict timing, reliability, and responsiveness demands of contemporary applications. This survey examines the diverse design techniques and scheduling strategies that are helpful in the evolution of RTOS in embedded systems. It starts with basic concepts such as preemptive scheduling on low-power microcontrollers, wherein hybrid algorithms such as round-robin with priority help improve effectiveness. We trace the evolution of RTOS being optimized for domain-based applications. In home automation, RTOS facilitate the smooth execution of tasks through good synchronization and real-time response to user demands. RTOS deployment over ARM-based platforms for augmented reality-powered traffic sign recognition addresses the issues of real-time in safety-critical automotive systems. Further, the compounded RTOS development is accompanied by dual-execution platforms that allow embedded programs to leverage both standard real-time control and general-purpose OS facilities without trading off timing guarantees. Leading thermal imaging platforms demonstrate how RTOS and heterogeneous SoCs enable real-time image processing with optimized power and performance. This survey highlights the architectural innovation and design practices that are enabling next-generation real-time embedded systems by synthesizing these various viewpoints.
