/**
|
* Defines a test for the family of CFFT transforms.
|
*
|
* The family of CFFT transforms includes:
|
*
|
* - arm_cfft_radix4_xxx
|
* - arm_cfft_radix2_xxx
|
* - arm_cfft_mag_xxx
|
*
|
* Where xxx can be f32, q31, or q15.
|
*
|
* @param fn_specifier Allowed values: radix4, radix2, mag.
|
* @param type_suffix Allowed values: f32, q31, q15.
|
*
|
* @param config_suffix Used to differentiate test names based configuration
|
* (in this case whether the ifft_flag is set or not.)
|
|
* @param comparison_interface Macro name used to compare reference and fut
|
* outputs.
|
*
|
* @param output_tpe The type of variable contained in the output
|
* (e.g. float32_t, uint32_t, etc).
|
*
|
* @param ifft_flag Determines whether the arm_cfft_instance_xxx is configured
|
* for an inverse FFT.
