WebAug 27, 2024 · Solution 1. A trap is an exception in a user process. It's caused by division by zero or invalid memory access. It's also the usual way to invoke a kernel routine (a system call) because those run with a higher priority than user code. Handling is synchronous (so the user code is suspended and continues afterwards). WebInterrupts will typically be used to execute a few lines of code by the ARM core (NVIC, interrupt handlers, etc.). Events don't necessary execute code but can signal …

Signals and interrupts behave in pretty similar ways. The difference is that signals happen to a process (which lives in a virtual environment), while exceptions are system-wide. Certain faults are flagged by the CPU as an exception, and then mapped to a signal that is delivered to the process by the kernel. djc006l
