LOGARITHM/INVERSE-LOGARITHM CONVERTER UTILIZING A TRUNCATED TAYLOR SERIES AND METHOD OF USE THEREOF
摘要
A converter which may be used for implementing either logarithmic or inverse-logarithmic functions is disclosed. The converter includes a memory (22), two multipliers (28 and 30), and two adders (32 and 34). The memory (22) stores a plurality of coefficients which are based on a second-order Taylor polynomial used to estimate a logarithmic or inverse-logarithmic function over a domain of input values. A method of using the converter is also disclosed.
