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.
