| /** |
| * Function: omxSP_FFTGetBufSize_C_FC32 |
| * |
| * Description: |
| * These functions compute the size of the specification structure |
| * required for the length 2^order complex FFT and IFFT functions. The function |
| * <FFTGetBufSize_C_FC32> is used in conjunction with the 32-bit functions |
| * <FFTFwd_CToC_FC32_Sfs> and <FFTInv_CToC_FC32_Sfs>. |
| * |
| * Input Arguments: |
| * |
| * order - base-2 logarithm of the desired block length; valid in the range |
| * [0,12] ([0,15] if BIG_FFT_TABLE is defined.) |
| * |
| * Output Arguments: |
| * |
| * pSize - pointer to the number of bytes required for the specification |
| * structure |
| * |
| * Return Value: |
| * |
| * OMX_Sts_NoErr - no error |
| * |
| * |
