    • Exemplary embodiments of the present invention comprise a method for compressing data for storage in memory. According to one embodiment, the method forms a set of values based on a monotonically ordered series of look-up table values. For one or more paired values in the set, the exemplary method generates a difference of the values in the pair. After replacing one of the values in the pair with a value based on the differences to modify the set, the exemplary method stores final values based on the modified set in memory. The present invention also comprises memory for storing the look-up table values. One exemplary memory comprises a decoder, an encoder, and one or more patterns of crisscrossed interconnect lines that interconnect the encoder with the decoder. The patterns of crisscrossed interconnection lines may be implemented on one or more planar layers of conductor tracks vertically interleaved with isolating material.
    • 本发明的示例性实施例包括一种用于压缩数据以存储在存储器中的方法。 根据一个实施例,该方法基于单调有序的查询表值序列形成一组值。 对于集合中的一个或多个配对值,示例性方法生成该对中的值的差异。 在使用基于差异的值替换该对中的一个值以修改该集合之后,该示例性方法将基于修改的集合的最终值存储在存储器中。 本发明还包括用于存储查找表值的存储器。 一个示例性存储器包括解码器,编码器以及将编码器与解码器互连的交叉互连线的一个或多个图案。 交叉互连线的图案可以在与绝缘材料垂直交错的导体轨迹的一个或多个平面层上实现。

    • The present invention describes a method and apparatus for performing logarithmic arithmetic with real and/or complex numbers represented in a logarithmic format. In one exemplary embodiment, an ALU implements logarithmic arithmetic on complex numbers represented in a logpolar format. According to this embodiment, memory in the ALU stores a look-up table used to determine logarithms of complex numbers, while a processor in the ALU generates an output logarithm based on complex input operands represented in logpolar format using the stored look-up table. In another exemplary embodiment, the ALU performs logarithmic arithmetic on real and complex numbers represented in logarithmic format. In this embodiment, the memory stores two look-up tables, one for determining logarithms of real numbers and one for determining logarithms of complex numbers, while the processor generates an output logarithm based on real or complex input operands represented in logarithmic format using the real or complex look-up tables, respectively.
    • 本发明描述了以对数格式表示的实数和/或复数进行对数运算的方法和装置。 在一个示例性实施例中,ALU对以对数极性格式表示的复数进行对数运算。 根据该实施例,ALU中的存储器存储用于确定复数对数的查找表,而ALU中的处理器使用存储的查找表基于以logpolar格式表示的复数输入操作数生成输出对数。 在另一个示例性实施例中,ALU对对数格式表示的实数和复数进行对数运算。 在本实施例中,存储器存储两个查找表,一个用于确定实数对数,另一个用于确定复数对数,而处理器基于使用真实的对数格式表示的实数或复数输入操作数生成输出对数 或复杂的查询表。
