1. 1. Hardware Architectures for the Inverse Square Root and the Inverse Functions using Harmonized Parabolic Synthesis

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Niclas Thuning; Tor Leo Bärring; [2016]
   Nyckelord :Approximation; Parabolic Synthesis; Newton-Raphson Metod; Inverse Square Root; Unary Functions; Elementary Functions; Second-Degree Interpolation; Arithmetic Computation; VLSI; ASIC; Technology and Engineering;

   Sammanfattning : This thesis presents a comparison between implementations of the inverse square root function, using two approximation algorithms; Harmonized Parabolic Synthesis and the Newton-Raphson Method. The input is a 15 bit fixed-point number, the range of which is selected so that the implementation is suitable for use as a block implementing the inverse square root for floating-point numbers, and the designs are constrained by the error, which must be < 2^(-15).

3. 2. Hardware Implementation of the Logarithm Function using Improved Parabolic Synthesis

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Jingou Lai; [2013]
   Nyckelord :Technology and Engineering;

   Sammanfattning : This thesis presents a design that approximates the fractional part of the based two logarithm function by using Improved Parabolic Synthesis including its CMOS VLSI implementations. Improved Parabolic Synthesis is a novel methodology in favor of implementing unary functions e.g. trigonometric, logarithm, square root etc. LÄS MER
