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.

- Efficient scheduling, synchronization, and IPC are essential for determined task execution.
- Understanding the differences between processes and tasks aids in better system design.
Key Concepts
- -- Process Management
- A core function of operating systems involving the management of process creation, scheduling, synchronization, and termination.
- -- RealTime Operating System (RTOS)
- An operating system that manages hardware resources and executes real-time tasks within defined timing constraints.
- -- Task Lifecycle
- The various states a task goes through in an RTOS, including Ready, Running, Blocked, Suspended, and Terminated.
- -- Scheduling
- The method of determining which task should receive CPU time at any given moment, crucial for meeting timing requirements.
- -- InterProcess Communication (IPC)
- Mechanisms that enable tasks to communicate and coordinate actions, critical for operations in multitasking systems.
