2. Process Management Strategies in Real-Time and Embedded Systems

Process management is crucial in real-time and embedded systems, focusing on creation, scheduling, synchronization, and termination of tasks for efficiency and predictability. It explores the distinctions between processes and tasks, their lifecycle, scheduling strategies, and inter-process communication mechanisms essential for effective task management in resource-constrained environments. The use of real-time operating system (RTOS) APIs and considerations for design efficiency in embedded systems are also emphasized.

    Process Scheduling In Real-Time Systems

    This section discusses the critical role of efficient and predictable task scheduling in real-time systems, highlighting key strategies such as priority-based and preemptive scheduling.

    Learning Practice

  • 2.5.1

    Priority-Based Scheduling

    Priority-based scheduling is a key strategy in real-time operating systems that ensures the highest priority tasks are executed first.

    Learning Practice

  • 2.5.2

    Preemptive Scheduling

    Preemptive scheduling allows a higher-priority task to interrupt a lower-priority task, ensuring critical processes run without delay.

    Learning Practice

  • 2.5.3

    Cooperative Scheduling

    Cooperative scheduling is a method where tasks voluntarily yield control, providing lower overhead but less timing control.

    Learning Practice

  • 2.6

    Process Synchronization

    This section covers process synchronization, which ensures correct and predictable behavior in multitasking systems through various mechanisms.

    Learning Practice

  • 2.7

    Context Switching
