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

   Författare :Jiajun Chen; Jianan Shi; [2016]
   Nyckelord :Harmonized Parabolic Synthesis; unrolled Newton-Raphson; power consumption.; Technology and Engineering;

   Sammanfattning : Nowadays, number inversion is of great significance and a complex arithmetical operator, especially the implementation in hardware. It provides a higher speed performance and lower power consumption. Initially, the conversion of the inputs to floating-point numbers contains sign, exponent, and mantissa parts. LÄS MER

3. 2. 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).
