摘要: | In this paper, a low-power Reed-Solomon (RS) decoder for STM-16 optical communications is presented. It mainly contains one (255,239) RS decoder and four 2K-bit embedded memory for correcting the received codewords. Except the novel syndrome calculator reducing half the syndrome computations, our proposal also features a modified Berlekamp-Massey algorithm in the key equation solver and a terminated mechanism in the Chien search circuit. The (255,239) RS decoder is implemented by 0.25mum CMOS 1P5M standard cells with gate counts of 32.9K and area of 2.03 mm(2). Simulation results show our approach can work successfully at the data rate of 2.5-Gbps and achieve 80% reduction of power dissipation on the average. |
