Area Reduction Of Syndrome Calculator For Strong Bose-Chaudhuri-Hocquenghem Decoder

Bose–Chaudhuri–Hocquenghem (BCH) codes have a widespread use to provide the error protection for multiple random errors in a binary code. BCH codes is commonly applied in various practical application such as advanced solid-state drives (SSDs), high-speed fiber optical communications system and wire...
