DSPLIB for TI C64x+ and C66x DSP architecture provides optimized implementation for FFT with assumptions for format and scaling of the input data. The application report provides guidance for users of DSPLIB for the following use cases:

• Efficient compute of single precision FFT using real input without reformatting data to complex format
• Fixed point FFT compute with no data scaling to avoid overflow

The content discussed benefits all DSPLIB users on C64x+, C674x and C66x DSP devices.
