Zynq UltraScale plus MPSoC Power Management

Release Date

RPU is a separate power island and can be turned-off when an application is only running on APU and doesn’t need any resources like TCMs in the RPU block. EEMI provides force_powerdown API to power down unused blocks. For applications that don’t use runtime PM, RPU can be turned off at boot time.

Powering down RPU block which is already idle saves around 70mW of power.
