Answer:
Interrrupt Latency means the time taken by the processor to
pass the control to ISR after the interrupt is raised.
Certainly this is the hardware feature.
Footprint of the OS matters because with the same compiler
and same optimization techniques, Different OS's will have
different footprint.
So this is can be looked upon while selecting the RTOS.
RTOS can be chosen looking at various API support it
provides. Synchronization support, Scheduler algos, and
memory management of the OS.
