DRA829V: Control power consumption by software

Part Number: DRA829V

Hi team,

I would like to ask you how to control power consumption at each cores like R5F, A72, and C7x.

I heard Jacinto7 series processor has no dynamic frequency changing feature.
So I wonder is it able that we can suppress power consumption without any low-power modes such as stand-by or sleeps.

In my understands, the power consumption on each cores is not changed by the type of instruction.
So I think that even if the cores run just only NOP, we cannot save the power.
But is it correct?

Best Regards,
Junpei
