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.

WebMeasuring Interrupt Latency 1. Introduction The term interrupt latency refers to the delay between the start of an Interrupt Request (IRQ) and the start of the respective Interrupt Service Routine (ISR). The interrupt latency is expressed in core clock cycles. 5.There is another exact definition-the number of clock cycles from the assertion of the Webto generate the early interrupt at the end of S/H + offset cycles. This interrupt is used to trigger the CLA control task. The CLA task implements the control logic to update the duty of the PWM output based on the read ADC value. The early interrupt feature and low interrupt latency of CLA allows the application to do any necessary
