This OS resembles what you would see in an "embedded systems" course. In addition to World 1 features, it can run multiple tasks and preempt their execution. However, everything still runs at EL1.

✅ Scheduler: cooperative & preemptive

✅ Memory allocator (simple)

✅ Task management (sleep, wait, exit, kill)

⛔ EL1 only ⛔ No virtual memory
