hbFFT2D

typedef struct {
  hbFFTPointSize nx;
  hbFFTPointSize ny;
  int8_t normalize;
} hbFFT2DParam;

FFT 2D operator parameter.

Member

Member Name	Description
`nx`	FFT points along the x-axis support the types in hbFFTPointSize.
`ny`	FFT points along the x-axis support the types in hbFFTPointSize.
`normalize`	Reserved parameter, defaults 0. Whether specification is performed is identified by 0 for non-specification and other values for specification.

Note

Specification refers to some form of scaling of the FFT results so that the results meet specific criteria or are easily interpreted.

int32_t hbFFT2D(hbUCPTaskHandle_t *taskHandle, hbHPLImaginaryData *dst,
                hbHPLImaginaryData const *src, hbFFT2DParam const *param);

The API for calling the FFT 2D.

When the imaginary data type is HB_HPL_DATA_TYPE_I16 or HB_HPL_DATA_TYPE_I32, its data layout format is only supported as HB_IM_FORMAT_SEPARATE. When the imaginary data type is HB_HPL_DATA_TYPE_F32, its data layout format is only supported as HB_IM_FORMAT_INTERLEAVED.

Parameter
- [out] taskHandle Task handle is responsible for the interaction of the operator with the UCP architecture.
- [out] dst Output dummy data including type, format and dimension information is consistent with the input.
- [in] src Enter the dummy data.
- [in] param Operator parameter.
Return Value
- Return 0 means the API was successfully executed, otherwise the execution failed.
