- Apr 24, 2026 Priority Inversion and the Protocols That Bound It How a low-priority lock holder can block a high-priority thread indefinitely, what inheritance and ceiling protocols each guarantee, and why both need the scheduler inside the lock. operating systems
- Oct 16, 2025 Priority Inversion and Inheritance How a low-priority lock holder can stall a high-priority thread, why inheritance repairs the ordering, and what it costs in unlock complexity and chained blocking. operating systems
- Jul 31, 2025 Measuring and Bounding Interrupt Latency What latency means at each point between a device asserting and a thread running, which mechanisms inflate the tail, and why the distribution rather than the average is the design target. operating systems
- May 21, 2025 Priority Inversion and How Bounded It Can Be Why a low-priority task holding a shared lock delays a high-priority one, how inheritance and ceiling protocols change the blocking term, and what each still leaves unbounded. embedded systems
- Apr 18, 2024 Worst-Case Response Time of a CAN Message Under Fixed-Priority Arbitration Why the identifier is a priority, how the blocking and interference terms of a response-time bound are computed for a bit-stuffed frame, and where the analysis stops being optimistic. embedded systems
