Claim 14:
15. The processing method according to claim 10, wherein the GPU and CPU are not integrated, the electronic device further comprises a memory controller including the first memory controller and the second memory controller, a video memory controller, an embedded controller, and a channel switch, and the first criteria includes that the electronic device is in a second mode; and
wherein the embedded controller is connected to the CPU and the channel switch and is connected to the video memory controller through the channel switch, and the channel switch is connected to the CPU, the GPU, and the video memory controller and is configured for a channel switch between a first communication channel between the CPU and GPU and a second communication channel between the CPU and the video memory controller, and the method further comprises:
in a first mode, the embedded controller controlling the first communication channel to be turned on and the second communication channel to be turned off through the channel switch, and in the second mode, the embedded controller controlling the second communication channel to be turned on and the first communication channel to be turned off through the channel switch,
wherein a memory capacity requirement of the CPU in the first mode is smaller than a memory capacity requirement of the CPU in the second mode.
