Overview

 
Xilinx provides user-parameterizable LogiCORE Reed-Solomon encoder and decoder cores for customers designing digital communication, mass storage, and multimedia systems. By using Xilinx Reed-Solomon solution users can significantly reduce implementation cost and accelerate time-to-market compared to fixed function ASSP alternatives. The cores support Xilinx Virtex/-E, Spartan-II, Spartan/-XL and XC4000 FPGA families. Implemented in Spartan-II, the Reed-Solomon solution costs less than $10 in high-volume making it ideal for many emerging high-volume markets.

The Basics of Reed-Solomon

Reed-Solomon is a type of Forward Error Correction (FEC) commonly used in data transmission and storage applications, such as wireless communication units, DSL modems, Digital TV, RAID, DVB and DVD products. By adding redundancy before data transmission and storage, a Reed-Solomon codec (encoder/decoder) can detect and correct errors for blocks of data. There are many different standards that are used in different applications, for example DVB, ATSC, and IESS-308.

Core Features

 
  • High-speed compact Reed-Solomon Decoder and Encoder
  • Automatically configured from user parameters (demo Decoder/Encoder)
  • Supports all major coding standards and custom implementations
  • Available for Virtex/-E, Spartan-II, Spartan/-XL, XC4000
  • Downloadable over the Internet gives instant access to latest releases
  • Incorporates Xilinx Smart-IP Technology for design predictability

Xilinx Smart-IP Technology

The definition for Xilinx Smart-IP technology is a combination of:

  • Xilinx FPGA architecture with segmented routing and distributed as well as block memory, which makes it well tailored to core implementation
  • Xilinx software and core features allowing predetermined placement and routing

The result is predictable design implementation where performance and functionality are consistent independently of core placement, number of cores used, surrounding user logic, device size, and used EDA tools. Xilinx Smart-IP Technology is vital for successful system-on-a-chip designs.
