用TI DSP芯片TMS320C6000实现FFT算法
内含程序代码和说明 The radix-4 FFT-Fixed-point digital signal processors (DSPs) have limited dynamic range to deal with digital
data. This application report proposes a scheme to test and scale the result output from each
Fast Fourier Transform (FFT) stage in order to fix the accumulation overflow. The radix-4 FFT
algorithm is selected since it provides fewer stages than radix-2 algorithm. Thus, the scaling
operations are minimized. This application report is organized as follows:
