Overview

Convolutional codes are widely adopted in wireless communication systems for forward error correction. Creonic offers you a certified open source Viterbi decoder IP core with AXI4-Stream interface that is capable of decoding most of the convolutional codes as defined by various standards.

Key features

  • Design-time configuration of encoder polynomials (different number of states and different code rates)
  • Support for recursive and non-recursive convolutional codes
  • Windowing technique for reduced latency and memory requirements (with acquisition)
  • Design-time configuration of quantization, maximum window size, RAM usage (distributed RAM vs. Block RAM)
  • Run-time configuration of block length
  • Run-time configuration of window length and acquisition length
  • Block-to-block on-the-fly configuration

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.
