Design and modeling of linear back projection (lbp) algorithm for field programmable gate array (FPGA)

Abstract

This paper focus on designing and modeling of linear back projection (LBP) algorithm for field programmable gate array (FPGA) application. The features provided in FPGA make it the most suitable for embedded system for optical tomography system in data acquisition system. The language supported by FPGA is a Hardware Description Language (HDL). However, manual coding for HDL code spend more time to program. In addition, it increase chances of human error. Therefore, the usage of Matlab Simulink has encouraged many researchers to use it in order to generate HDL code while minimize human error. The LBP algorithm is designed by using Matlab Simulink. From the Matlab Simulink, the HDL code will be generated automatically by using HDL coder which is provided by MathWorks. The HDL code obtained will be downloaded into an FPGA platform of Altera DE2-115. The result obtained shows that the LBP algorithm has been successfully modelled. Therefore, this approach provides an effective method flow for the LBP algorithm to implement in FPGA.
