摘要
本文简要介绍了RS译码器中的修正Euclid算法(MEA),并详细分析了如何减少实现MEA带来的延迟时间,在现有的减少延迟时间的思想上,提出了一种新的高效低延迟的MEA实现结构。仿真结果表明,和其他已有的结构相比,在相同的符号处理速率下,这种结构能够极大地减少延迟时间,从而降低实现复杂度。
In this paper, the author briefly describes the modified Euclid's algorithm, and analyzes how to reduce the latency for recursive cell of modified Euclid's algorithm in detail. Improved from some known ideas, a new recursive cell architecture is proposed. The simulation results illustrate that compared with other architectures, this architecture can greatly reduce the latency which leads to decrease of complexity while ensuring other performances.
