A position k of the most significant bit within a binary number is located. Then, all bits that are less significant than position k within the binary number are assigned as a fractional portion of a ... 12/08/05 - 20050273481 - Pipelined real or complex alu A method and ALU for implementing logarithmic arithmetic in a multi-stage pipeline is described herein. According to one embodiment, a master function is decomposed into two or more sub-functions. Memory associated with the pipeline stores a look-up table for each stage of the pipeline, where each table represents function values ... 09/22/05 - 20050210090 - Logarithm determining method and apparatus for the same A logarithm determining method for use in a digital processor is provided. The method is for converting an input number x into a logarithm L by a base b. The logarithm L includes an integer part In and a mantissa part Ma. The method represents numbers in a fixed-point format. ... 08/11/05 - 20050177605 - Computation of logarithmic and exponential functions Efficiency of computation of logarithmic and exponential functions may be improved using multiplication by pre-computed coefficients to obtain intermediate products. ... 06/23/05 - 20050138095 - Method for base two logarithmic estimation The present invention provides for implementing a base two logarithmic estimation function in a general purpose processor. The present invention provides for partitioning an input value into a biased exponent value and a mantissa. Whether the biased exponent value is negative is determined. A first intermediate value from the mantissa ... ### FreshPatents.com Support |
