    摘要： A touch sensor senses the presence of an object at one of a plurality of channels on a surface of the touch sensor, wherein proximity of the object to the touch sensor results in a change in capacitance at the position of the channel. The touch sensor includes a drive circuit and a charge sensing circuit, each coupled to each of the channels. The charge sensing circuit includes at least one charge measurement capacitor. A measurement cycle is applied to the touch sensor having a drive portion and a sense portion. During the drive portion a charge is applied to the channels and therefore the charge measurement capacitors of the touch sensor, and during a sense portion the charge measurement capacitors are discharged by a predetermined amount and the remaining charge on the charge measurement capacitors is measured.

    摘要： An iterative method for generating a series of output signal values from a series of input signal values is described. Iterations of the method comprise the steps of obtaining a current input signal value for the current iteration, comparing the current input signal value with an output signal value determined in a previous iteration, updating a counter value determined in the previous iteration based on the result of the comparison between the current input signal value and the previous output signal value such that the updated counter value replaces the counter value determined in the previous iteration, determining a slew value based on the counter value; and adding the slew value to the previously determined output signal value to generate a new current output signal value. Thus different slew values may be added to the previous output signal to obtain a new output signal. The counter value is updated so that its value reflects recent trends in the input signals. E.g. if the input signal is on an upward trend, the counter value may achieve a relative high value, for example because it is incremented each time an input signal exceeds a previously determined output signal. The magnitude of the slew values may increase as the counter value increases, thereby allowing the output signals to more rapidly track changes in the input signals.

    摘要翻译： 描述了从一系列输入信号值产生一系列输出信号值的迭代方法。 所述方法的迭代包括以下步骤：获取当前迭代的当前输入信号值，将当前输入信号值与在先前迭代中确定的输出信号值进行比较，根据先前迭代中确定的计数值， 当前输入信号值与先前输出信号值之间的比较，使得更新的计数器值替换在先前迭代中确定的计数器值，基于计数器值确定转换值; 并将所述转换值加到先前确定的输出信号值以产生新的电流输出信号值。 因此，可以将不同的转换值添加到先前的输出信号以获得新的输出信号。 更新计数器值，使其值反映输入信号的最新趋势。 例如。 如果输入信号处于上升趋势，则计数器值可以达到相对较高的值，例如因为每当输入信号超过预先确定的输出信号时它增加。 当计数器值增加时，转换值的大小可能会增加，从而允许输出信号更快地跟踪输入信号的变化。

    摘要： Methods, apparatus and systems for large number multiplication. A multiplication circuit is provided to compute the product of two operands (A and B), at least one of which is wider than a width associated with the multiplication circuit. Each of the operands includes contiguous ordered word-wide operand segments (Aj and Bi) characterized by specific weights j (integer from 0 to k) and i (integer from 0 to m). The multiplication circuit executes a matrix of word-wide operand segment pair multiplication operations. Multiplication operations are performed on a pair of rows at one time. For each pair of rows, a pair of corresponding Bi word-wide operand segments are read from a memory and word-wide operand segment pair multiplication operations (Aj*Bi) are iteratively performed for each of k+2 columns. For each column a maximum of two additional memory read operations and one memory write operation is required.
