Instance structure for the floating-point CFFT/CIFFT function.
uint8_t riscv_cfft_radix2_instance_f16::bitReverseFlag |
flag that enables (bitReverseFlag=1) or disables (bitReverseFlag=0) bit reversal of output.
uint16_t riscv_cfft_radix2_instance_f16::bitRevFactor |
bit reversal modifier that supports different size FFTs with the same bit reversal table.
uint16_t riscv_cfft_radix2_instance_f16::fftLen |
length of the FFT.
uint8_t riscv_cfft_radix2_instance_f16::ifftFlag |
flag that selects forward (ifftFlag=0) or inverse (ifftFlag=1) transform.
float16_t riscv_cfft_radix2_instance_f16::onebyfftLen |
value of 1/fftLen.
const uint16_t* riscv_cfft_radix2_instance_f16::pBitRevTable |
points to the bit reversal table.
const float16_t* riscv_cfft_radix2_instance_f16::pTwiddle |
points to the Twiddle factor table.
uint16_t riscv_cfft_radix2_instance_f16::twidCoefModifier |
twiddle coefficient modifier that supports different size FFTs with the same twiddle factor table.
