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.
