process()

int RX_buffer_demodulator::process	(	float2 **__restrict__	in,
		float2 **__restrict__	out
	)

PAcket handler for DSP class. This method process information pointed by the in parameter and write the output in the memory pointed by out parameter. Both in and out are CPU RAM pointers already allocated. The memory input memory is NOT modified. The output memory has to be already allocated. This function assumes that there is enough memory allocated to write the full output.
