FIR Filter Benchmarks

This repository contains benchmarks validating the performance of various FIR filtering algorithms. Current algorithms include:

• JUCE FIR Filter
• JUCE Convolution
• std::inner_product
• SIMD-acclerated inner product

For further explanation of each algorithm, please see this writeup.

Results

So far, I have the results of the benchmarks from a Windows machine (a 2017 Dell laptop with an Intel i7 CPU), and a Mac machine (a 2019 MacBook Pro with an Intel i9 CPU).

For more results, see the ./results/figures/ directory.

Benchmark results and algorithm optimization from the community is greatly appreciated!

Running

If you wish to build and run the benchmarks for yourself, use the following steps (requires cmake):

# clone repository
$ git clone https://github.com/FIRBenchmarks
$ cd FIRBenchmarks/

# update submodules
$ git submodule update --init

# build with CMake
$ cmake -Bbuild -DCMAKE_BUILD_TYPE=Release
$ cmake --build build --config Release

# run benchmarks
$ ./build/FIRTesting_artefacts/FIRTesting
# On Windows use this instead: ./build/FIRTesting_artefacts/Release/FIRTesting.exe
