The flow according to the embodiment of the invention can be applicable to the processor 1100, or performed by the processor 1100. In an implementation, the respective steps in the flow can be performed by integrated logic circuits in hardware, or instructions in software, in the processor 1100. The processor 1100 can be a general-purpose processor, a digital signal processor, an application specific integrated circuit, a field programmable gate array, or another programmable logic device, discrete gate, transistor logic device, or discrete hardware component. The respective methods, steps, and logic block diagrams disclosed in the embodiments of the invention can be implemented or performed. The general-purpose processor can be a micro processor, or can be any conventional processor, etc. The steps in the method according to the embodiment of the invention can be performed directly by a hardware processor, or performed by a combination of hardware and software modules in the processor. The software module can be located in a random memory, a flash memory, a read-only memory, a programmable read-only memory, an electrically erasable and programmable memory, a register, or another storage medium known in the art. The storage medium is located in the memory 1101, and the processor 1100 reads the information in the memory 1100, and performs the steps in the flow with the hardware thereof.
Specifically the processor 1100 is configured to read and execute program in the memory 1101:
