FFT Applications: Radar Signal Processing, Fast convolution, Spectrum Estimation, OFDM-based Modulation/demodulations
Efficient VLSI architectures (parallel processing) are required for real-time processing.
However, most systems still employ DSP processors (e.g., TI C3x/C5x) for computations (fast algorithms like DIT and DIF FFT).
VLIW (Very Long-length Instruction Word)-based processors (TI C6x) need new programming skills to utilize the two parallel MAC units.
