Web1 de out. de 2001 · Latency is pretty easy to measure. Simply instrument each ISR with an instruction that toggles a parallel output bit high when the routine starts. Drive it low just as it exits. Connect this bit to one input of an oscilloscope, tying the other input to the interrupt signal itself. This simple setup produces a breathtaking amount of information.

Web18 de mai. de 2024 · The SMI is the highest-priority interrupt on the system, and places the CPU in a management mode. This mode preempts all other activity while SMI runs an interrupt service routine, typically contained in BIOS. Unfortunately, this behavior can result in latency spikes of 100 microseconds or more. WebIn computing, interrupt latency refers to the delay between the start of an Interrupt Request (IRQ) and the start of the respective Interrupt Service Routine (ISR).
