[NIRF-Group]

Description

Description-Separate-1

Overview

This IP performs normal/ shortened Reed-Solomon encoding for code word length(n)=255, data word length(k)=239.

Description

National Instruments has partnered with Prentice Hall to bring you large portions of in-depth technical topics from several PTR RF and Communications books, including Digital Communications: Fundamentals and Applications, 2nd Edition. This series of content is designed for a broad range of audiences, from experts who want to review a specific topic to students who need easy-to-understand documentation for their projects.

Steps to Implement or Execute Code

The IP specification is as mentioned below:

• Implements Reed-Solomon code (255, 239)
  • Code word length (n)= 255 symbols
  • Data word length (k)= 239 symbols
  • Field generator polynomial p(x) = x^{8 + x}4 + x^{3 + x}2 + 1
  • Code generator polynomial g(x) = (x + a^{0)(x + a}1)(x + a^{2)…(x + a}15); a=0x02
• Supports code shortening
• Maximum clock rate=80MHz
• Supports data rates <=clock rate
• Fully synchronous design , with speed optimization

Requirements

Software:

LabVIEW FPGA 2010

Hi

Thanks for the code, but I am not sure how to use it, I could not find some library files when the labview load the file, like ni5640Rtemplete.lvlib, is there a way to get it?

Kind Regards
