    • A word recognition device uses an associative memory to store a plurality of coded words in such a way that a weight is associated with each character of the alphabet of the stored words, wherein equal weights correspond to equal characters. To perform the recognition, a dictionary of words is first chosen; this is stored in the associative memory according to a pre-determined code; a string of characters which correspond to a word to be recognized is received; a sequence of weights corresponding to the string of characters received is supplied to the associative memory; the distance between the word to be recognized and at least some of the stored words is calculated in parallel as the sum of the difference between the weights of each character of the word to be recognized and the weights of each character of the stored words; the minimum distance is identified; and the word stored in the associative memory having the minimum distance is stored.
    • 字识别装置使用关联存储器来存储多个编码字,使得权重与存储字的字母表的每个字符相关联,其中相等的权重对应于相等的字符。 要进行识别,首先选择字典; 根据预先确定的代码将其存储在关联存储器中; 接收与要识别的字对应的一串字符; 与所接收的字符串对应的权重序列被提供给关联存储器; 要被识别的单词和至少一些所存储的单词之间的距离被并行计算为要被识别的单词的每个字符的权重与所存储的单词的每个字符的权重之差的总和; 确定最小距离; 存储具有最小距离的关联存储器中存储的字。

    • Presented is an energy efficient charge pump, that includes at least two stages. Each stage has input and output nodes, which correspond to terminals of a first transistor. A boost capacitor is tied to the input node, and a second capacitor is tied to an internal node, which is also the gate terminal of the first transistor. A second transistor is located between the input node and the internal node, and has a gate coupled to the output node. A driving signal generator generates ramped voltage driving signals and non-ramped voltage driving signals. Attached to the driving signal generator is a phase driver that applies the ramped voltage driving signals to the boost capacitor and applies the non-ramped voltage driving signals to the second capacitor. Also presented also is method of driving a charge pump, such as the one described above, where the boost capacitor is driven with a ramped voltage signal, while the second capacitor is driven with a non-ramped voltage signal.
