Reed Solomon Encoder / Decoder II

The Reed-Solomon (RS) Compiler II offers a fully parameterizable RS encoder and decoder. RS encoders and decoders are widely used for error detection and correction in a wide range of digital signal processing (DSP) applications for storage, retrieval, and transmission of data. RS Compiler II is designed to support optical transport network (OTN) applications.

Throughput:

  • Supports up to 10 Gbps with multiple core instantiation
  • Provides 2.5 Gbps throughput for Stratix® series FPGAs
  • Provides 1.28 Gbps throughput for Cyclone® series FPGAs
  • Supports up to 16 interleaved channels

The RS Compiler II generates a fully parameterizable RS function, allowing you to set the following parameters:

  • Number of bits per symbol (8)
  • Number of symbols per code word (range: 204 to 255 )
  • Number of check symbols per code word (range: 2 to 66)
  • All valid field polynomials

The RS function offers the following other features:

  • Intellectual property (IP) functional simulation models for use in Intel FPGA supported VHDL and Verilog HDL simulators
  • Easy-to-use IP Toolbench interface:
    • Generates parameterized encoder or decoder
    • Generates customized test bench and customized Tcl script
  • Avalon®Streaming (Avalon-ST) interfaces
  • DSP Builder ready

Typical expected performance and utilization figures for this MegaCore® function are provided in the Reed-Solomon Compiler II User Guide.
