A Low-Complexity Reed-Solomon Decoder for GPON

摘要：

This paper presents a low-complexity parallel Reed-Solomon (RS) (255,239) decoder architecture using a novel pipelined variable stages recursive Modified Euclidean (ME) algorithm for GPON system. The pipelined four-parallel syndrome generator is proposed. The time multiplexing and resource sharing schemes are used in the novel recursive ME algorithm to reduce the logic gate count. The new key equation solver can be shared by two decode macro. The proposed decoder operates at a clock rate of 78 MHz and the throughput is 2.5Gb/s. The decoder is implemented in Altera Stratix Ⅱ device. The resource utilization is reduced about 40％ comparing to the conventional method.
