在总结已有的FFT实现方法基础上,提出了一种通用FFT处理器的设计;这种FFT实现结构可支持非基2点FFT,硬件资源得到了优化,处理速度可以满足高清晰度数字电视地面传输系统的要求。
On the basis of summarizing the existing FFT implementation methods, a general FFT processor design is proposed. This FFT implementation structure can support non-base 2-point FFT, the hardware resources are optimized and the processing speed can meet the needs of high definition digital television Ground transmission system requirements.
