摘要
基于移位加的CORDIC算法是最简单超越函数硬件实现方法。本文介绍了这种算法的工作方式和计算超越函数的具体过程,设计了一个80位嵌入式超越函数运算器,并从该处理器的设计构思和系统结构到处理器内部各单元的设计进行了比较详尽的阐述,最后给出了对该设计进行软件仿真的结果。
The CORDJC algorithm based on shift and add operation is the simplest algorithm of transcendental function.CORDIC working mode and application detail were presented in this paper, and an 80-bit embedded calculator for the transcendental function was designed.The thinking of the design of the calculator, its architecture and specific units are described in detail.Software simulations are made and the results are given.
