基于FPGAIP核的FFT实现
Implementation of FFT Based on FPGA IP Core
【摘要】 对于FFT而言,很多领域都提出了其高速实时运算的要求。利用FFT IP核实现FFT算法,并在CycloneⅡ系列的EP2C70F896C8器件上设计出处理速度为69.58 MHz的24位512点复数FFT处理器需29.3μs,该方法具有效率高、速度快、周期短、灵活性强等特点。仿真结果表明此方法具有良好性能。
【Abstract】 For FFT,requirements for the property of its high-speed,and real-time computing has been proposed in many areas.The paper implements FFT algorithm by using FFT IP core,in Cyclone Ⅱ series of EP2C70F896C8 device designs to handle speeds of 69.58 MHz 24 b 512-point complex FFT processor with 29.3 μs.The method has the characteristics of high efficiency,high-speed,short-cycles,flexibility and so on.The simulation results indicate that this method has good performance.
