Abstract: An embedded megamodule and an embedded CPU enable power-saving through a combination of hardware and software. The CPU configures the power-down controller (PDC) logic within megamodule and can software trigger a low-power state of logic modules during processor IDLE periods. To wake from this power-down state, a system event is asserted to the CPU through the module interrupt controller. Thus the entry into a low-power state is software-driven during periods of inactivity and power restoration is on system activity that demands the attention of the CPU.

Abstract translation: 嵌入式巨型模块和嵌入式CPU通过硬件和软件的组合实现节能。 CPU在兆模块内配置掉电控制器（PDC）逻辑，并且可以在处理器空闲周期期间软件触发逻辑模块的低功耗状态。 要从此掉电状态唤醒，系统事件将通过模块中断控制器发送到CPU。 因此，进入低功耗状态是在非活动期间进行软件驱动，并且电源恢复是需要CPU注意的系统活动。
