A comprehensive handbook on QuRT (Qualcomm Real-Time Operating System), the RTOS running on Qualcomm's Hexagon DSP inside Snapdragon-powered devices. Covers the full development workflow including SDK setup, SCons build system, thread creation internals (TCB layout, stack frame initialization, context switching), synchronization primitives (mutexes with priority inheritance, condition variables, signals, barriers, semaphores), memory management (TCM vs DDR, cache coherency for shared memory, memory pools for O(1) allocation), hardware-backed timers for periodic DSP workloads, and interrupt handling via QuRT's thread-based ISR model. Includes working C code examples throughout, from a basic hello-world thread to a producer-consumer pipeline and sensor fusion patterns.
