Improving Accuracy in Mitchell's Logarithmic Multiplication Using Iterative Multiplier for Image Processing Application
Binary Logarithms, Deeksha R Shetty, Savitha Patil · 2013
The logarithmic of a binary number may be determined approximately from the number itself by simple shifting and counting. Since the logarithms used ar e approximate there can be errors in the result. This paper prese nts a simple and efficient logarithmic multiplier with the possibilit y to achieve an arbitrary accuracy through an iterative procedure. Digital image processing is used in variety of application .Many algorithm used in image processing include convolution. In this co ding is done using VHDL for the FPGA. Synthesis and simulation is done using Xilinx and MATLAB is used to convert input image in to a matrix form which is convolved with the kernel value using proposed multiplier and the result is again convert ed back into a image form using m.file.
