The CPU is overheated or a program stalls. However, no matter which of the above cases causes the inconvenience of the user, the user is left with a bad impression on the brand electronic device.

In order to make the overall operation of the electronic device smoother, the processing speed of the processor must be increased. In view of the fact that the image processor is almost the basic device of the electronic device with the display screen, the image processor is shared with the operation of the central processing unit. The amount called General Purpose Processor (GPGPU) technology is also evolving. However, because the design orientation between the image processor and the central processor is quite different from the type to be calculated, there are many difficulties in development. Therefore, how to more effectively allocate the tasks to be performed by the electronic device to the image processor or the central processing unit that has the idle processing to be processed, so that the overall operation of the electronic device is smoother, thereby reducing the traditional central processing. If the operation of the device is too large and the electronic device is overheated or the power consumption is too fast, that is, the processor that processes the task to be processed can be determined according to the power consumption or heat dissipation of the image processor and the central processing unit. A subject worth studying.
