Abstract: Embodiments of this application disclose a flash memory access method and apparatus, and relate to the field of chips, so as to alleviate a problem in the conventional technology that a conflict occurs when a plurality of software subsystems running on one chip access a flash memory. A specific solution is: The method is applied to a system on chip including an access controller and a plurality of processor cores, where the plurality of processor cores are separately connected to the access controller through a bus, a plurality of software subsystems run on the plurality of processor cores, different software subsystems run on different processor cores, and a power supply of the access controller is different from power supplies of the plurality of processor cores, or the access controller shares a power supply with a first processor core that runs a first software subsystem.

Abstract: A data transmission method and an apparatus are provided, to resolve a problem that network communication between a communications apparatus and an external network device cannot be ensured. A network protocol stack is deployed on both a wireless communications unit and a service processing unit, and the wireless communications unit is responsible for distribution. This can ensure processing of a network service and a throughput of a wireless network when a processing capability of the wireless communications unit is weak. The network protocol stack is deployed on the wireless communications unit. When the service processing unit is powered off, the wireless communications unit can still communicate with an external device, for example, remote wakeup.

Abstract: A communication method and apparatus are provided, to resolve a problem that timeliness of data transmission is affected because a communication connection is not established in time. A network protocol stack is deployed for each of a service processing unit and a wireless communication unit in a first communication apparatus. In this way, before the service processing unit enters a working mode, the wireless communication unit may establish a transmission channel with a second communication apparatus based on the deployed network protocol stack. After the service processing unit enters the working mode, the service processing unit exchanges data with the second communication apparatus through the transmission channel based on the deployed network protocol stack.
