Change the GPIO State with Registry.
If time is so important for your project the following items can be of great importance to you:
when you use SDK Xilinx original functions for change in the state of GPIO like XGpioPs_WritePin it makes 1.5 us time for changing but if you use Registry this time reduces to 600ns and it can help you so much.
In this Project, I elaborate that how you can get the amount of any Pin in Any bank of Xilinx registry.
for further information or any question please don't hesitate to contact me.
