Abstract
This application discloses a method for prolonging sleeping time of CPU. After CPU enters sleeping state, interrupt controller delays reporting deferrable external interrupts to the CPU, with the delay time set or as default. This application also provides a device corresponding to the method. This application can prolong the sleeping time of CPU in all kinds of intelligent electronic devices, and make the CPU enter a deep sleeping mode, thereby reducing power consumption substantially without affecting system performance.
