The device is divided into a number of separate voltage domains, each containing specific processing cores and peripherals. This division enables the device to achieve lower power dissipation profiles by allowing the power supplies to unused domains to be completely turned off.
Each PSC in the device has several power domains that can be turned on for operation, or off to minimize power dissipation. The Global Power Sleep Controller (GPSC) is used to control the power gating of various power domains. Clock gating to each logic block is managed by the Local Power Sleep Controllers (LPSCs).
For modules with a dedicated clock or multiple clocks, the LPSC communicates with the PLL controller to enable and disable that module's clock at the source. For modules that share a clock with other modules, the LPSC controls the clock gating logic for each module.
