Overview

This is a very high speed 16 state maximum a posteriori (MAP) soft-in-soft-out (SISO) triple interleaved error control decoder with log-likelihood-ratio outputs for both the data and parity bits.

Key features

  • 16 state soft-in-soft-out (SISO) maximum a posteriori (MAP) triple interleaved error control decoder and systematic recursive convolutional encoder
  • Up to 95 Mbit/s decoding speed for all states
  • Rate 1/2, 1/3, or 1/4 with optional punctured inputs
  • 6-bit received data, 8-bit soft-in and soft-out data for information and parity bits for all rates
  • 8-bit branch metric inputs for rate 1/2
  • Optional code polynomials
  • Optional block decoding with or without tail
  • Optional max-log-MAP or log-MAP algorithm with 9 or 17 programmable SNR's
  • Continuous sliding block algorithm with sliding block lengths of 32 or 64
  • Low decoding delay (400 or 784 CLK cycles)
  • No external RAM required
  • Asynchronous logic free design
  • Ideal for iterative decoding of CCSDS turbo codes
  • Available as BIT/MCS files for download into Xilinx Virtex and Virtex-E field programmable gate arrays (FPGA) or EDIF/VHDL core. Actel, Altera and Lattice FPGA cores available on request.

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.
