What is Lottery Scheduling?
Lottery scheduling is a probabilistic CPU scheduling algorithm that gives each process a number of lottery tickets proportional to its desired share of the CPU…
What is Priority Inversion?
Priority inversion is a scheduling hazard where a high-priority task is indirectly blocked by a low-priority task holding a lock it needs, while an unrelated m…
How Does Thread Scheduling Work?
Thread scheduling is the mechanism by which the OS (or a user-space runtime) decides which of the runnable threads gets CPU time next, typically driven by prio…
What is a Real-Time Operating System (RTOS)?
A real-time operating system is one that guarantees a task completes within a specified deadline, prioritizing predictable, bounded response time over raw aver…
What Are Nested Interrupts and How Are They Handled?
A nested interrupt occurs when a higher-priority interrupt is allowed to preempt a currently executing lower-priority interrupt handler, so the CPU suspends th…
What Makes Embedded OS Design Different from a General-Purpose OS?
Embedded OS design prioritizes deterministic, bounded-latency execution and a tiny, predictable memory and code footprint over the throughput and general flexi…
