The solution from Creonic for data rates of up to 1 Gbit/s offers outstanding efficiency in terms of implementation complexity. John Porter, CTO of Cambridge Communications Systems and convinced Creonic customer, says: “The Creonic WiMedia IP core runs at over twice the speed and uses half the logic of any competing products“. Area and energy efficiency played a decisive role during the LDPC code design process. With this unified approach not only outstanding efficiency is obtained, but also excellent error correction performance, outperforming Viterbi decoders by up to 3 dB. At the same time, a throughput of hundreds of Mbit/s can be achieved even on low-cost FPGAs.
