Overview

5G NR is the mobile broadband standard of the 5th generation. A new rate compatible structure for LDPC codes are employed for channel coding to fulfill the broad applications supported by the standard.

Creonic’s 5G LDPC Decoder IP Core provides a perfect solution for this new LDPC structure with high level of flexibility while maintaining high throughput and low latency as required by the standard.

Key features

  • Support for 3GPP Release 15 5G LDPC decoding
  • Support for base code rates from 22/68 to 22/26 for basegraph 1
  • Support for base code rates from 10/52 to 10/14 for basegraph 2
  • Depuncturing is included in the core

Benefits

  • Throughput up to 574 Mbits/s
  • Low-power and low-complexity design
  • Block-to-block on-the-fly configuration
  • AXI4-Stream handshaking interfaces for seamless integration
  • Design-time configuration of throughput for optimal resource utilization
  • Faster convergence due to layered LDPC decoder architecture
  • Early stopping criterion for iterative LDPC decoder, saving a considerable amount of energy
  • Collection of statistics (decoding success, iterations needed)
  • Available for ASIC and FPGAs (AMD Xilinx, Intel)

Applications

  • 5G-NR 3GPP Rel.15 modem chipset for base station (BS) or user equipment (UE)
  • Applications with highest demands on forward error correction
  • Applications with the need for a wide range of code rates and block length

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.
