[−][src]Struct cmsis_dsp::transform::Q15RealFft
Runs an FFT on Q1.15 fixed-point real numbers
Implementations
impl Q15RealFft[src]
pub fn new(
size: u32,
direction: Direction,
output_order: OutputOrder
) -> Result<Self>[src]
size: u32,
direction: Direction,
output_order: OutputOrder
) -> Result<Self>
Initializes an FFT with the specified size
Valid size values are 32, 64, 128, 256, 512, 1024, 2048, and 4096. This function returns an error if the size value is not valid.
pub fn run(&self, input: &[I1F15], output: &mut [i16])[src]
Runs an FFT on fixed-point values
The output type depends on the size of the FFT. To determine how to interpret the output bits, refer to the table in the arm_rfft_q15 function documentation at https://www.keil.com/pack/doc/cmsis/DSP/html/group__RealFFT.html#ga00e615f5db21736ad5b27fb6146f3fc5 .
