There are several ways to reduce the interrupt latency in Embedded C. The interrupt latency depends on many factors. Following is a list of some factors:
* Platform and interrupt controller
* CPU clock speed
* Timer frequency
* Cache configuration
* Application program etc.
So, we can easily reduce the interrupt latency by using the proper selection of platform and processor. We can also reduce the interrupt latency by making the ISR shorter and avoid to calling a function within the ISR.
