fft

An IoT product based on FreeRTOS, using CoAP for communication, changing a LED band's colors at 60Hz based on audio frequency and amplitude, captured using a microphone (at 44.1 kHz).

Create fast Fourier transform (FFT) processing hardware for your FPGA or CPLD. Use this tool to create an FFT core of any width or length. Customize to your project's needs. FFT hardware is generated in the SystemVeilog (SV) hardware description language (HDL).
