摘要

提出了一种新的基于符号位预测的CORDIC算法。将经典CORDIC的任意迭代变换为简单的矩阵乘法是一种有效的方法。同时，该算法是基于同步数据触发架构(SDTA)实现的。实验结果表明，与gcc3.2.2支持的数学库相比，在给定的Neuron微处理器下，基于我们的CORDIC版本测试的超越函数的平均加速可达283%。

A New CORDIC Algorithm and Software Implementation Based on Synchronized Data Triggering Architecture

A new CORDIC algorithm based on sign bits prediction is presented. It is an effective method for transforming arbitrary iterations of classic CORDIC to simple matrix multiplications. At the same time, this algorithm is implemented based on synchronized data triggering architecture (SDTA). Experimental results show that the average speed-up of transcendental functions tested based on our version CORDIC compared with mathematic library supported in gcc3.2.2 is up to 283% under the given Neuron microprocessor.
