摘要:
在传统的CORDIC算法的基础上提出一种改进算法,然后给出实现正弦、余弦函数的运算的混合算法.该算法在不影响数据精度要求的情况下,不仅可以减少迭代次数和所需的ROM存储空间,还有利于结构的流水线设计,减少系统的时钟周期,提高速度.最后在Altera公司的Cyclone系列芯片EP1C3T100C6上予以实现.仿真结果证明:此算法比传统算法具有高运算速度与低资源的优势,最高工作频率可达到184.77 MHz,比传统算法提高了11.84%,在结构上较传统的CORDIC算法节省近17.35%硬件资源.
Abstract:
Based on the traditional CORDIC algorithm, an improved algorithm is proposed, and then a hybrid algorithm is given to realize the operation of sine and cosine functions. Without affecting the data accuracy requirements, the algorithm can not only reduce the number of iterations and the required ROM storage space, but also facilitate the pipeline design of the structure, reduce the clock cycle of the system, and improve the speed. Finally, it was implemented on Altera’s Cyclone series of chips EP1C3T100C6. The simulation results show that this algorithm has the advantages of high operation speed and low resources compared with traditional algorithms, and the maximum working frequency can reach 184.77 MHz, which is 11.84% higher than that of traditional algorithms, and saves nearly 17.35% of hardware resources compared with traditional CORDIC algorithms.
