Creonic Releases Ultrafast BCH Decoder IP Core, Processing One Codeword per Clock Cycle

Kaiserslautern, Germany, June 16, 2023 - Creonic GmbH, a leading IP core provider in the field of communications, today announced immediate availability of its Ultrafast BCH Decoder. Its unique pipeline architecture allows it to decode one BCH codeword per clock cycle, achieving tremendous data rates. For instance, a coded block size of 1023 bits with 973 payload bits and the capability to correct up to 5 random bit errors can achieve a throughput of 1 Tbit/s when running at a clock frequency of 1 GHz on an ASIC technology.

These high data rates make it the ideal fit for die-to-die communication or other applications with exceptionally high throughput requirements, such as optical communications. If there are just few bit errors scattered within the codeword, it can be a suitable replacement for Reed-Solomon (RS) decoders, as BCH coding comes with significantly lower decoding complexity, reducing size, latency, and power consumption.

At design-time, the decoder can be adjusted with regard to block size, error correction capabilities, and the number of pipeline stages. Information about the correctness of an input codeword is provided with a latency of one clock cycle. Corrected codewords are available with a latency of about 4 to 14 clock cycles, depending on the parameterization.

The IP core is available specifically for ASIC app-lications. However, for a wide range of para-meterizations, it is also a viable solution for FPGA tech-nologies such as AMD Xilinx and Intel, achieving data rates in excess of 100 Gbit/s.

The BCH decoder is provided as Verilog or VHDL source code, along with a self-checking testbench and a bit-accurate software model.
