Embodiments disclosed herein relate to reducing a power consumption of an electronic device while maintaining some functionality of the electronic device while the electronic device is in a low power mode. The device may be in the low power mode due to a battery level being below a threshold. If the battery level is below the threshold, the electronic device may enter the low power mode. However, before entering the low power mode, some functionality of an application processor may be transferred to a communication controller. Once the functionality is transferred, the application processor may be disabled to reduce power consumption while maintaining functionality of the application processor. The electronic device may also utilize various communication protocols to communicate with a peripheral device. Even though the electronic device may be in the low power mode, the communication controller may be used to cause the peripheral device to perform various actions.

Various techniques and circuit implementations for power reduction management in integrated circuits are disclosed. Certain techniques include the implementation of rate control circuits to control a clock rate for circuits associated with a communication fabric in an integrated circuit. The clock rate may be reduced based trigger signals received from power delivery trigger circuits coupled to the integrated circuit and voltage regulators providing power to the integrated circuit. Additional techniques may include the use of rate limiter circuits in a memory pipeline.
