How do you reduce interrupt latency?

1.	How do you reduce interrupt latency?
Answer» Interrupt latency can be reduced by making a short interrupt routine if interrupt priorities are not allowed by the hardware. In such a case interrupt routine which is STARTED cannot be INTERRUPTED by another interrupt. It will be better to AVOID disabling the INTERRUPTS in any method. In such a case the interrupt has to wait for the NEXT one to be allowed.
