运算流水线的实现和优化

文章在对流水线性能进行分析的基础上，以双精度浮点运算流水线为例子，阐述了实现多条运算流水机制的方法。并对单条流水线，从设计结构和运算的分段两个方面详细介绍了设计的优化方案，并对优化后流水化设计和传统流水设计进行了可靠性和速度的比较，其速度可以提高近1倍。

Implementation and Optimization of Arithmetic Pipeline

For one thing, base on the analysis of performance of pipehne, implementation of multi-arithmetic pipeline is discussed in this article illustrated by double precision floating-point arithmetic pipeline. For another thing, this paper introduces the optimization scheme in design structure and arithmetic separation for single pipeline in detail. At last, the optimized pipeline design is compared in speed and reliability with traditional single circle design in the thesis. The speed of optimized design can nearly doubled.
