Rank order filter design using maximum magnitude generator

摘要

Design of Rank order filter is used to sort the maximum value and assign maximum rank value among multiple inputs. Here rank order filter is designed in digital logic design. Implementation of rank order filter is based on maximum magnitude generator. This maximum magnitude generator (MMG) is used to select the maximum value among n values. Rank order filter assigns rank for the maximum value. Here 4 inputs, 4 bit maximum magnitude generator are used k and k - 1. These outputs are given to the AND gate with one of the input as inverted magnitude generator output (k - 1). Here input vectors are connected to the multiplexers and filter output is transmitted to the output of final rank value. The proposed design is simulated using Xilinx software.
