When a Correct Braking Decision Is 2 s Late: Real‑Time, RTOS, and Watchdog Basics
The article explains why a braking controller that computes the right result but delivers it two seconds late is considered a failure, outlines the unique constraints of embedded systems, describes the five‑layer architecture, distinguishes strong versus weak real‑time, and details the roles of RTOS, HAL/BSP, soft‑hardware co‑design, and watchdog timers.
