This allows the library to provide all SIMD variants with a single source code, however this limits support to the compilers which have the vector extensions, which are currently GCC and Clang.\n\n## Benchmarks\n\nThe following benchmarks have been computed on x86_64 Linux with Intel(R) Core(TM) i7-6500U CPU @ 2.50GHz.\n\n| AVX single precision                               | AVX double precision                                 |\n| -------------------------------------------------- | ---------------------------------------------------- |\n| ![fir-avx-float](benchmark-data/fir-avx-float.png) | ![fir-avx-double](benchmark-data/fir-avx-double.png) |\n| ![iir-avx-float](benchmark-data/iir-avx-float.png) | ![iir-avx-double](benchmark-data/iir-avx-double.png) |\n\n| SSE single precision                               | SSE double precision                                 |\n| -------------------------------------------------- | ---------------------------------------------------- |\n| ![fir-sse-float](benchmark-data/fir-sse-float.png) | ![fir-sse-double](benchmark-data/fir-sse-double.png) |\n| ![iir-sse-float](benchmark-data/iir-sse-float.png) | ![iir-sse-double](benchmark-data/iir-sse-double.png) |\n\nThe following benchmarks have been computed on aarch64 Linux with Odroid-C2.\n\n| A64 single precision                               | A64 double precision                                 |\n| -------------------------------------------------- | ---------------------------------------------------- |\n| ![fir-a64-float](benchmark-data/fir-a64-float.png) | ![fir-a64-double](benchmark-data/fir-a64-double.png) |\n| ![iir-a64-float](benchmark-data/iir-a64-float.png) | ![iir-a64-double](benchmark-data/iir-a64-double.png) |\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjpcima%2Ffast-filters","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjpcima%2Ffast-filters","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjpcima%2Ffast-filters/lists"}
