Power Management

•AM35x power management features:

–Single voltage and power domain

–Multiple clock domains

–Single Operating Voltage and Frequency

–Low power mode (standby)

•Power, Reset and Clock Management (PRCM) module controls power management

•One voltage supply to device processors and peripherals.

•Supports dynamic clock gating for power management through clock domains.

–A clock domain is a group of modules or subsections of device that share a common clock

–By gating the clock to each domain, it is possible to cut a clock to a group of inactive modules to lower their active power consumption.
