Hi,
I am doing interface between ps to pl in ZYNQ processor. I need some clarifications on interface.
1. what is the frequency of AXI4 clock frequency.
2. for interface have 3 ways like (GPIO, ACP), I need some technical document to use the methods in vivado 2014.1.
Thanks & Regards

The frequency of the AXI clock in your design depends on your hardware implementation. The Zynq is a programmable device and you can set the AXI clock frequency based on your design as well as the maximums for your specific device and speed grade.
For the Zynq device on the ZedBoard and MicroZed the default clock rate defined using the Vivado tools will be 100 MHz.
You might want to take the time to run through some of the training material available. A good place to start would be the Avnet Zynq Speedway workshops:
Developing Zynq
-7000 All Programmable SoC Software (Vivado 2013.3)
Developing Zynq-7000 All Programmable SoC Hardware (Vivado 2013.3)
which will give you a better idea of how the various interfaces work. Once you have generated a working Zynq hardware design in Vivado and 'exported' this design to the SDK you can open up the system.mss file. Here you will find links to example code for each of the available peripherals.
