Forward error correction is imperative in most communication systems. Applications like short-reach optical communications have a limited power and area occupation budget for encoder and decoder implementation. In this brief, we propose high-throughput low-latency Reed Solomon (RS) encoder and decoder architectures, compatible with a recently proposed class of generalized RS codes. The architectures are synthesized in TSMC 65 nm CMOS technology, showing a significant performance improvement with moderate hardware cost and power consumption. Throughput is increased by $ {\times 11.5}$ for the encoder, with respect to a conventional architecture, while the latency is reduced by ${\times 10.3}$ . These improvements respectively amount to ${\times 14.7}$ and ${\times 7.5}$ for the decoder.

一类用于短距离光通信的广义 Reed-Solomon 码的高吞吐量低延迟编码器和解码器

在大多数通信系统中，前向纠错是必不可少的。短距离光通信等应用对于编码器和解码器的实现具有有限的功率和面积占用预算。在这个简介中，我们提出了高吞吐量、低延迟的 Reed Solomon (RS) 编码器和解码器架构，与最近提出的一类广义 RS 代码兼容。这些架构采用 TSMC 65 nm CMOS 技术合成，在适度的硬件成本和功耗下显示出显着的性能提升。吞吐量增加了 $ {\times 11.5}$ 对于编码器，相对于传统架构，延迟减少了 ${\times 10.3}$ . 这些改进分别相当于 ${\times 14.7}$ 和 ${\times 7.5}$ 对于解码器。
