Detailed Description

FFT Calculation block

Constructor & Destructor Documentation

dcf::CFFT2DCalcBlock::CFFT2DCalcBlock	(	const dcf::Manager &	manager,
		int	direction = `1`,
		bool	normalize = `true`
	)

Default FFT calculations block constructor

with DCF Manager provided. Direction should be 1 for direct fft and -1 for inverse fft. By default spectrum will be normalized.

virtual dcf::CFFT2DCalcBlock::~CFFT2DCalcBlock ( )

virtual

Destructs object.

Member Function Documentation

void dcf::CFFT2DCalcBlock::calcModule	(	size_t	dim_x,
		size_t	dim_y,
		float *	re,
		float *	im,
		float *	mod
	)

Calculates module mod for complex data (re, im). All arrays should be predefined.

bool dcf::CFFT2DCalcBlock::cuda_fft ( )

protected

Calculates FFT using CUDA. Returns false on error.

void dcf::CFFT2DCalcBlock::cuda_set_data	(	size_t	dim_x,
		size_t	dim_y,
		float *	re_data,
		float *	im_data
	)

protected

Set data for CUDA (construct or not new fft plan depended on new sizes provided)

dcf::error_t dcf::CFFT2DCalcBlock::free_device ( )

protected

Free selected device

int dcf::CFFT2DCalcBlock::getDirection ( ) const

inline

Gets current fft direction.
