How to get cpu clock value from qsys

Hello,

 

I try to understand how I can find hps cpu clock and hps perpheral clock.

As I understand they are not found in qsys.

 

But I found the following calculator https://rocketboards.org/foswiki/Documentation/PreloaderClockingCustomization131

 

which gives value for all plls.

Is it correct that:

cpu clock = mpu_base_clk (C0)

peripheral clock = mpu_periph_clk

 

Thank you,

ranran

Hi,

 

The mpu_base_clk is the microprocessor unit base clock,

 

The peripheral clock is a Clock for microprocessor unit snoop control unit (SCU) peripherals, e.g.: the general interrupt controller (GIC).

 

More info regarding the clock you can refer here I've attached the page link to the clock page:
