`#include <dsp.h>`
`#include "e_fft.h"`

## Functions
fractcomplex sigCmpx[FFT_BLOCK_LENGTH] | __attribute__ ((section(".ydata, data, ymemory"), aligned(FFT_BLOCK_LENGTH *2 *2)))

## Detailed Description

Allocate memory and initialize the sigCmpx array.

sigCmpx is the main array in which the FFT will be done. So you must to fill this array with your values to perform the FFT.
This array has the following size: 64, 128, 256, 512 depending the choice you have made in fft.h
