Atomic operations allow thread-safe access to shared resources without the use of locks in multi-threaded systems. On Cortex-M0/M0+ multi-core microcontrollers, atomic operations can be implemented using special instructions like LDREX and STREX or by disabling interrupts during critical sections. The choice depends on performance requirements and how critical the shared resource is. What are atomic…

In the ARM architecture, interrupts are handled by the processor’s interrupt controller and vectored interrupt controller. The interrupt controller receives interrupt requests from various sources and determines the priority of the interrupts. The vectored interrupt controller uses the priority to determine which interrupt should be handled first when multiple interrupts are pending. ARM processors typically…
