摘要
Disclosed herein are a mixed-radix pipelined Fast Fourier Transform (FFT) processor and an FFT processing method using the same. The mixed-radix pipelined Fast Fourier Transform (FFT) processor includes a first radix chain, a second radix chain, an input buffer, and an output buffer. The first radix chain includes first radix processors that are connected in series to each other. The second radix chain includes second radix processors that are connected in series to each other, and is connected in series to the first radix chain. The input buffer performs index mapping on a sequence input to the first radix chain. The output buffer generates a final FFT output by performing index mapping on a sequence generated using outputs of one or more of the first and second radix chains.
