摘　　要：本文研究了WFA仲裁算法,WFA采用的固定轮转优先级的仲裁算法,没有考虑到各端口队列的长度和消息包的缓急情况。本文针对WFA算法存在的这种不足提出了一种改进算法,该算法易于实现、仲裁更公平,通过软件建模的方式进行了模拟,模拟结果表明,优化具有较好的效果。This paper studies Wave Front Arbiter algorithm. WFA adoption of a fixed-order-cycle priority algorithm, and have no in consideration of length and age of packages. To settle the problems existing in WFA, an improved algorithm is proposed in this paper. It is easier to realization and arbitrament fairer. Software model of this improved algorithm is built, and the analysis of simulate result showed that the optimization algorithm is efficient.
