PROCESSING APPARATUS, AND RELATED CONTROL METHOD FOR LOW-POWER-CONSUMPTION STANDBY

WIPO Patent Application WO/2024/036452

A1

Disclosed in the present application are a processing apparatus, and a related control method for low-power-consumption standby. The present application is characterized in that the processing apparatus comprises a power management unit, a chip system and an on-chip memory, wherein the power management unit supplies power to the chip system by means of a first power domain, and supplies power to the on-chip memory by means of a second power domain; the power management unit is used for receiving a first indication sent by the chip system, which first indication is used for indicating that the processing apparatus has entered a standby state, and the power management unit is also used for controlling the first power domain to turn off, and keeping some or all power sources of the second power domain in a power supply state; after the processing apparatus enters the standby state, the chip system is in a powered-off state and some or all devices of the on-chip memory are in a powered-on state; a first control signal is sent to the on-chip memory, and the first control signal is used for keeping the on-chip memory in a first mode, and in the first mode, the on-chip memory stores currently stored data. By using the embodiments of the present application, standby power consumption can be reduced, thereby increasing a standby duration and improving the user experience.
