Abstract :
We propose a Reed-Solomon (RS) codec processor that can have programmable error-correction number of 1 to 10, and codeword length of 8 to 255. The proposed RS codec processor includes an encoder and a decoder. Especially in the decoder, we use a modified Fermat algorithm to reduce the complexity of the division. By using the cell library of the TSMC 0.35 μm CMOS technology, the proposed RS codec processor was implemented with a die size of 5.1×5.0 mm2. It can operate at 50 MHz to yield the throughput rate of 50 Msamples per second where each sample is 8 bits
