The SD-FEC core is a highly flexible soft-decision FEC decoder and LDPC encoder offering the following features:

  • Function configurable between either:
    • LDPC decode or encode of customer-specified Quasi-cyclic (QC) codes, including standard and custom, or
    • Turbo decode of codes used by LTE
  • Peak throughput of the order:
    • 1.78 Gb/s turbo decode @ 6 iterations
    • 2.84 Gb/s for LDPC decode @ 8 iterations
    • 19.82 Gb/s for LDPC encode
  • Scalable implementation
    • Multiple instantiations on a device (see Placement Location Guidelines for SD-FEC IP Core)
  • High bandwidth AXI4-Stream interfaces
Note: Throughput depends on the codes and how they are mixed and the actual clock frequency on the device. See Clocking for further details.
