Discrete Fourier Transform (DFT) libraries are one of the most critical software components for scientific computing. Inspired by FFTW, a widely used library for DFT HPC calculations, we apply compiler technologies for the development of HPC Fourier transform libraries. In this work, we introduce FFTc, a domain-specific language, based on Multi-Level Intermediate Representation (MLIR), for expressing Fourier Transform algorithms. FFTc is composed of: A domain-specific abstraction level (FFT MLIR dialect), a domain-specific compilation pipeline, and a domain-specific runtime (working in progress). We present the initial design, implementation, and preliminary results of FFTc.
