Okay, I realized how I was confusing clock tick (for timekeeping) and interrupt
latency and why the result were not the ones I expected.
I still have one question, is there a macro to choose/impose the processor
frequency ?

Good point. Thanks.
Would you have any idea concerning my other question ? (why I get the same
result for interrupt latency with different values of Tick per microsecond )

Yeah, hardware limits to 1.5ns if we take in account the max frequency of the
cortex. (That was the more or less 1ns =) )

Hi,
I was trying to measure the interrupt latency in RTEMS with a Xilinx Zynq
Zedboard (cortex A9).
I modified the c file in classic_signal example to measu
