Abstract: A touch sensing system including a touch interface and a processing unit is provided. The touch interface has multiple independent touch blocks. The processing unit is coupled to the touch interface. The processing unit includes an interpolating unit. The interpolating unit interpolates multiple spacing points between two adjacent touch blocks along a first direction to generate multiple first coordinate values. The processing unit determines a central block according to a threshold value and sensing values corresponding to the touch blocks, selects at least one touch block adjacent to the central block as a peripheral block, and determines a touch position on the touch interface according to the number of the spacing points, the sensing value corresponding to the peripheral block, a position of the peripheral block, the sensing value corresponding to the central block, and a position of the central block.

Abstract: A power-saving control circuit and method suitable for circuits including a first-in-first-out (FIFO) register is provided. In the present invention, a logic circuit is disposed between two circuit modules with data transmitted in between. When there is data input into the FIFO register, the logic circuit activates a clock signal of the circuit module in the receiving end for reading the data. When all the data stored in the FIFO register is read, the clock signal is turned off so that the power consumed by the clock signal is reduced without affecting the data transmitting efficiency and the purpose of power-saving is achieved.

Abstract: A positioning algorithm for edge portion of touch panel is provided. Dummy sensing lines surrounding a touch panel are provided. The x-axis and y-axis coordinate ranges of x-axis and y-axis sensing lines of the touch panel are determined. When the touch panel is touched, an x-axis sensing line, a y-axis sensing line, and a dummy sensing capacitance generated by the dummy sensing lines are located. Whether the corresponding x-axis sensing capacitance of the x-axis sensing line is smaller than or equal to the x-axis dummy sensing capacitance is determined. If so, an x-axis coordinate value is obtained according to the x-axis sensing capacitance and the dummy sensing capacitance. Whether the corresponding y-axis sensing capacitance of the y-axis sensing line is smaller than or equal to y-axis dummy sensing capacitance is determined. If so, a y-axis coordinate value is obtained according to the y-axis sensing capacitance and the dummy sensing capacitance.

Abstract: A power-saving control circuit and method suitable for circuits including a first-in-first-out (FIFO) register is provided. In the present invention, a logic circuit is disposed between two circuit modules with data transmitted in between. When there is data input into the FIFO register, the logic circuit activates a pulse signal of the circuit module in the receiving end for reading the data. When all the data stored in the FIFO register is read, the pulse signal is turned off so that the power consumed by the pulse signal is reduced without affecting the data transmitting efficiency and the purpose of power-saving is achieved.
