摘 要: 为了提高FFT(Fast Fourier Transformation)处理数据的实时性,本文研究了16位1024点FFT并提出了几种有效的优化方案。在Xilinx公司Virtex-E系列FPGA上实现了工作频率50MHz以上、流水线型、基22单路径反馈结构(R22SDF)FFT处理器。仿真和性能评估结果表明本FFT处理器的有较高的性能。 This paper presents optimized implementations of 16-bit 1024-point pipeline FFT processor with the R2ZSDF architecture on FPGA(Field-Programmable Gate Array). To mprove the ability of FFT's processing data in real time, different optimization techniques were explored. With these techniques, our FFT processor has been realized on Virtex-E FPGA with operation frequency above 50MHz, pipeline, R2SDF architecture. Validation and performance evaluation results show that the FFT processor has higher performance.
