Viterbi Decoder

Viterbi Decoders are used in systems where data are transmitted and subject to errors before reception.

Overview

Viterbi Decoders are used in systems where data are transmitted and subject to errors before reception. Compatible with many common standards such as DVB, 3GPP2, IEEE802.16, HiperLAN, Intelsat IESS-308/309, the Viterbi Decoder LogiCORE™ IP, along with other forward error correction cores from Xilinx offers highly-flexible concatenated codecs. The Viterbi Decoder LogiCORE IP consists of two basic architectures: a fully parallel implementation which gives fast data throughput and a serial implementation which occupies a small area. The core also has a puncturing option, giving a large range of transmission rates and reducing the bandwidth requirement on the channel. Puncturing can also be carried out externally to the decoder and the erasure pins in the erasure bus ERASE can be asserted to indicate the presence of null-symbols.

Key features

  • High-speed, compact Viterbi Decoder.
  • Two architectural options (parallel or serial) allow user to optimize for throughput or resource utilization.
  • Very low latency option.
  • Parameterizable constraint length, convolution codes, traceback length and soft data width.
  • Decoder rates from 1/2 to 1/7.
  • Supports multi-channel applications.
  • Compatible Encoder core available
  • For use with Vivado® IP Catalog and Xilinx System Generator for DSP™

Practical Considerations of LDPC Decoder Design in Communications Systems

This paper covers some practical aspects of designing the LDPC decoder starting from comparison between different techniques, different decoders parameters or standards, the effect of those parameters on the LDPC performance, also it discusses the algorithm selection process, and floating point implementation process.

Audio Transport in DisplayPort VIP

DisplayPort uses Secondary Data Packets (SDPs), which are transported over the Main-Link that are not main video stream data. This allows it to carry audio and video simultaneously. The VIP supports audio transmission both in the original mode as defined in the specification as well as just as any other SDP being transmitted.
