WebJun 30, 2010 · 4. Interrupts are hardware interrupts, while traps are software-invoked interrupts. Occurrences of hardware interrupts usually disable other hardware interrupts, but this is not true for traps. If you need to disallow hardware interrupts until a trap is served, you need to explicitly clear the interrupt flag. WebJul 7, 2024 · You simply run the code, look at the trace, compute the delta time (typically manually) and convert CPU cycles to microseconds. Unfortunately, the trace gives you one instance of execution, and you might have to look further down the trace capture to find the worst-case execution time. This could be a tedious process.

WebInterrupts are always polled before the second CPU cycle (the operand fetch), but not before the third CPU cycle on a taken branch.
