... new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress ...

fft_8point.c.rar
8点基二fft
Fast Fourier Transform (FFT).
Using 8 points, takes about 1.2 ms to execute one FFT.
Sets up General Purpose Timer 1 to generate events at 10 kHz.
Will produce 10 kHz output on T1PWM and T1PWM pins.
