    • An electronic device includes at least a pair of opposite touch keys defined on a touch panel, a touch sensing unit, a storage unit, a touch control unit, and a CPU. The storage unit stores a key-coordinate area relation list, which defines a relationship between the keys and the coordinate areas. A touch sensing unit included in the touch control unit generates signals in response to user touches on the keys. A touch area determining module included determines the coordinates touched according to the signals, and searching the key-coordinate area relation list to determine the coordinate areas including touched coordinates, and determines whether the touched coordinates distributed in both of the coordinate areas corresponding to the one pair of the pair of opposite touch keys. Then the key determining module determines an “OK” key is touched if yes. The CPU executes a function corresponding. A related method is also provided.

    • A multi-core processor and a frequency conversion device thereof as well as a method of communication between the cores are disclosed. Each processor core of the multi-core processor includes a frequency conversion device, which includes a multi-bit state changing means, a multiple selector, a frequency conversion coefficient register, a multi-input OR gate and a clock-gating circuit unit. A common original clock is sent to the frequency conversion device of each processor core at work. The frequency conversion device real-timely reads the value of the frequency conversion coefficient register of a corresponding processor core and receives data transmission valid signals from other processor cores. By gating the common original clock, a frequency conversion function of the processor core is completed. In the invention, the dynamic frequency conversion function of a multi-core processor is achieved, the frequency conversion coefficient control may be performed by each processor core independently, and a highly effective synchronous communication may be maintained between the processor cores, so as to reduce the overall running consumption of the processor and save power on different processor cores of the multi-core processor or on different IP modules in SOC.
