Overview

In order to achieve higher throughput, the turbo decoder uses up to 8-parallel MAP decoder. The sliding window algorithm is used to reduce the internal memory sizes. Turbo decoder accepts input LLR's with 8-bit precision and outputs the hard decision bits after six full iterations.

Key features

  • 8-bit precision for input LLR
  • 13-bit precision for internal calculations
  • Provides automatic normalization for internal calculations to avoid hardware overhead
  • Supports full 3GPP-LTE and UMTS block size range is supported
  • Supports rate 1/3 coded input
  • Supports MAX-log-MAP with scaling factor
  • 8 parallel-decoding units (with options of 4/2/1 parallel decoding units for smaller block length codes)
  • Sliding window algorithm for internal memory reduction
  • Uses parallel internal interleaved/de-interleaver
  • Payload throughput of up to 43.2 Mbit/s at 6 iterations (111 MHz on Xilinx-XC6VLX760-1FF1760)
  • Supports a configurable maximum number of iterations and controllable termination for achieving greater throughput

What’s Included?

  • Synthesizable Verilog
  • System Model (Matlab) and documentation
  • Verilog Test Benches

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.
