✅ TASK 1: RTOS Part-3: Automating the Scheduling with Round-Robin Policy
🎯 Objective:
The primary objective of this session is to understand time-sliced task execution within a Real-Time Operating System. Interns will study how a scheduler manages multiple threads sharing the exact same priority level. By implementing a Round-Robin policy, you will learn how the kernel uses the system tick to enforce equal CPU time-sharing, ensuring no single thread hogging resources starves out equal-priority tasks.

✅ TASK 2: RTOS Part-4: Efficient Blocking of Threads
🎯 Objective:
The primary objective of this session is to master CPU resource preservation through efficient thread blocking. In complex embedded configurations, having a task sit in a continuous loop waiting for a hardware flag wastes massive processing cycles. Interns will explore kernel states to understand how tasks voluntarily yield execution and enter a “Blocked” state, allowing the CPU to perform other meaningful work until the exact resource or delay timer expires.

🎯 Objective:
The primary objective of this session is to dissect the core definition of “Real-Time” computing, focusing entirely on determinism and preemption.
