106 : small FFT
- Author: Rice Shelley
- Description: Computes a small fft
- GitHub repository
- Clock: 1000 Hz
How it works
Takes 4 4-bit signed inputs (real integer numbers) and outputs 4 6-bit complex numbers
How to test
after reset, use the write enable signal to write 4 inputs. Read the output for the computer FFT.
