2048点FFT在TMS320C240x定点DSP上的实现2048点FFT在TMS320C240x定点DSP上的实现-2048-point FFT in TMS320C240x fixed-point DSP to achieve the 2,048 points FF T in TMS320C240x fixed-point DSP Implementation

Kiss FFT is a small and simple FFT library. It has no complicated platform-specific optimizations, can do either fixed or floating point with just a recompile, and is efficient enough for all but the most demanding applications.

ifft The Altera® FFT MegaCore® function uses block-floating-point (BFP) arithmetic internally to perform calculations. BFP architecture is a trade-off between fixed-point and full floating-point architecture.-ifft The Altera® FFT Meg
