The
Creonic CCSDS AR4JA LDPC IP support the LDPC coding schemes as defined
by the CCSDS standard. The LDPC codes with rates 1/2, 2/3 and 4/5, block
lengths 1024, 4096 and 16384 are specially designed for deep-space
missions, but the excellent error correction performance makes it the
ideal fit for further applications with highest demands on forward error
correction.

Key benefits of the decoder:
- Gains of up to 3 dB compared to Viterbi decoders
- Low-power and low-complexity design
- Layered LDPC decoder architecture, for convergence
behavior that is twice as fast as non-layered LDPC decoders - Early stopping criterion for iterative LDPC decoder, saving a considerable amount of energy
- Optional fixed number of iterations for fixed latency of blocks with the same code rate and block length
- Configurable amount of LDPC decoding iterations for trading-off throughput and error correction performance
- Collection of statistic information (number of iterations, decoding success, number of modified bits)
Key benefits of the encoder:
- High-throughput, low-latency encoder core
- Low-power and low-complexity design
- Deliverable includes VHDL source code or synthesized netlist, VHDL testbench, and bit-accurate Matlab, C or C++ simulation model
-
Available for ASIC and FPGAs
