摘要

作者分析了基于位串行、无冗余并行和冗余算法、流水线等CORDIC模块的离散傅里叶变换处理器的成本效益。根据处理一个频率输出的时间和所需模块的数量，分析了每个处理器的性能。结果表明，基于cordic的DFT处理器在超大规模集成电路中是一种有前途的解决方案，可用于大范围的输入比特率。

Discrete Fourier transform processors using CORDIC

The author presents an analysis of the cost-effectiveness of discrete Fourier transform processors, based on CORDIC modules such as the bit-serial, parallel with non-redundant and redundant arithmetic, and pipelined. The performance of each processor is analyzed with respect to the time to process one frequency output and the number of modules required. It is shown that the CORDIC-based DFT processor is a prospective solution in VLSI to be used for a wide range of input bit rate.<>
