CG2271 Lect9: Scheduling Analysis

In this video, we look at the various Scheduling Policies used by an OS. We first review the various terms like Worst-Case Execution Time (WCET) Wort-Case Response Time (WCRT), Deadline, Necessary and Sufficient, etc. Using Critical Analysis, we can understand if a task set that fulfills the necessary condition but not the sufficient condition can still be schedulable using a fixed-priority system. In the later part, we review the use of Semaphores with Interrupts to trigger the actions of various tasks. Welcome to our comprehensive video series on Real-Time Operating Systems (RTOS) for ARM microcontrollers! This series is designed for engineers, students, and developers looking to master RTOS concepts, with a focus on ARM Cortex-based microcontrollers. Each video covers crucial topics ranging from architecture design to advanced RTOS features like multi-threading, semaphores, and message queues. In this series, we’ll dive into the following key topics: RTOS architecture design: Learn how to structure real-time systems for performance and efficiency. Input/Output operations: Explore how to manage I/O effectively in RTOS-based systems. Interrupt handling: Understand how to implement and manage interrupts in real-time applications. Timers and Pulse-Width Modulation (PWM): Master the use of timers and PWM for precise control. Serial communication protocols: Work with UART, I2C, and SPI to implement robust communication between devices. RTX RTOS: Explore the widely-used Keil RTX RTOS for ARM-based microcontrollers and learn how to utilize its core features. Multi-threading: Learn how to implement and manage multiple threads efficiently in RTOS. Mutex and semaphores: Ensure thread synchronization and safe resource sharing using mutexes and semaphores. Message queues and mailbox: Understand inter-process communication with message queues and mailboxes. Events and flags: Manage event-driven programming using event flags. Virtual memory management: Learn how to handle virtual memory in RTOS systems for complex applications. Our in-depth tutorials and practical examples will give you the knowledge you need to design, develop, and optimize real-time systems using ARM microcontrollers. Why Watch This Series?
