Ultrafast BCH Decoder
BCH codes are widely used where bit errors are scattered randomly within the codeword. The Creonic Ultrafast BCH Decoder is capable of processing an entire BCH codeword per clock cycle in a pipelined way. Therefore, tt achieves outstanding data rates.
The design can be parameterized at design-time to support different codeword sizes and code rates. Latency can be adjusted by insertion or removal of pipeline register stages.
Applications
- Die-to-die communication
- Free-space optical (FSO) communication
-
Further applications with the need for
tremendous data rates
Performance Figures
- Coded throughput of up to 163.5 Gbit/s at 320 MHz (FPGA, 511 codeword bits)
- Coded throughput of up to 122.4 Gbit/s at 480 MHz (FPGA, 255 codeword bits)
-
Latency in the range of 4 to 14 clock cycles (466 payload bits, 511 codeword bits))
