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。
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.
