Systolic　算法和结构实现固定点平滑计算

Systolic Algorithm and Architecture for Fixed-point Smoother

本文提出一种适合于并行计算的平方根算法及相应的脉动（Ｓｙｓｔｏｌｉｃ）结构以实现固定点平滑计算。与以前的串行算法比较，这种算法在计算的实时性及数值稳定性方面都得到了提高．文中还对平滑计算的速度及处理器的利用率作了简要分析。

A square-root algorithm for parallel fixed-point smoother is proposed in this paper. An efficient systolic array architecture for performing the algorithm is also proposed. Compared with other algorithms before,the property of real-time and numerical stability are improved. The time-steps for a complete iteration and the utilization for the processors are also analysized.
