Low-complexity Reed-Solomon decoder for Blu-ray Disc applications

摘要

This paper presents a low-complexity Reed-Solomon decoder design for Blu-ray Disc (BD) applications. By employing the developed folding scheme, the resulting decoder design, based on the modified Euclidean (ME) algorithm proposed by Truong, can effectively reduce the hardware cost and meet the throughput requirement of BD applications. Compared with the related work, our development not only provides a lower area requirement but also has a simpler control mechanism. Experimental results show that the developed decoder can operate at 200MHz with a total gate count of 49,168, and achieve a throughput rate of 1.55Gbps for BD applications when implemented with the TSMC 0.18µm process.
