采用路径搜索的并行RS编码器IP自动生成方法

Automatic generation of parallel RS encoder IP based on datapath search method

摘要:

根据RS编码器的特点，提出了一种可以实现任意编码多项式、任意并行倍数的并行RS编码器IP的自动生成方法。该方法基于并行计算中数据路径的自动搜索求得编码矩阵，生成有限域运算电路，从而使得编码器所有HDL代码可以由软件自动生成。设计了一款9倍并行RS(255,223)码编码器，综合结果表明：结合门级优化策略，所生成的并行编码器使用资源较少，且电路工作频率相对原始单倍处理电路基本保持不变。

Abstract:

Parallel encoders are often used in fiber communication networks. This study introduced an automatic generation method for parallel Reed-Solomon(RS) code encoder Intellectual Property(IP) based on the automatic searching for datapath in parallel computation and auto-generation of the Gaolis computation circuit. The uniform structure made its HDL codes easily generated by software. The synthesis result of the designed 9*parallel RS(255,223) encoder showed that with gate-level optimization, this automatic implementation used less resources, and maintained the same working frequency with the original circuit.
