Dynamic voltage and frequency scaling is a technique that can be used on the logic voltage domains (VDD_MPU_L, VDD_IVAHD_L, VDD_DSPEVE_L and VDD_GPU_L), independently of one another. Upon a current or predictive performance request, determined by software according to ad hoc algorithms or heuristics, software can configure the PRCM module to change the OPP of a voltage domain. For an increase in performance, the voltage is first raised, and then the frequency is increased. For a decrease in performance, the frequency is first decreased, and then the voltage is dropped.
