Should the AHB and APB interfaces on Mali-55 be clocked on the same frequency?

Applies to: Mali-55


AHB clock and APB clock must have the same clock source. If not, it will break the functionality of Mali55.

If you have 2 different clocks for AHB and APB in your system, then you will have to generate a new clock for the APB interface on Mali-55. This new APB clock must be of the same frequency as AHB.
