The PowerWise AVS EMU can be used without the Powerwise Interface and the APC IP. Using an AVS enabled EMU in a system where the processor does not contain a hardware based PWI master is straight forward and can be done using a GPIO port and the PWI protocol software driver. Application Note (AN1460), describes how to emulate a PWI master using general purpose input/output pins (GPIOs) – and the PWI master software driver. This can be done with a variety of processors, ASICs, and SoCs. PowerWise AVS EMU with the SPMI or PWI interface may also be used if the processor or SoC only contains the PWI or SPMI interface master but no AVS controller. In both GPIO emulated or hardware-interfaced cases the benefits of adaptive voltage scaling will not be obtained without the use of APC.
