[2.3.0] - 2020-05-09

Hi everyone!

VOLK 2.3 is out! We want to thank all contributors. This release wouldn't have been possible without them. We saw lots of great improvements.

On GNU Radio 'master' VOLK was finally removed as a submodule.

Currently we see ongoing discussions on how to improve CPU feature detection because VOLK is not as reliable as we'd like it to be in that department. We'd like to benefit from other open source projects and don't want to reinvent the wheel. Thus, one approach would be to include cpu_features as a submodule.

Highlights

  • Better reproducible builds
  • CMake improvements
    • ORC is removed from the public interface where it was never supposed to be.
    • CMake fixes for better usability
  • Updated and new CI chain
    • TravisCI moved to new distro and does more tests for newer GCC/Clang
    • Github Actions
      • Add Action to check proper code formatting.
      • Add CI that also runs on MacOS with XCode.
  • Enforce C/C++ coding style via clang-format
  • Kernel fixes
    • Add puppet for power_spectral_density kernel
    • Treat the mod_range puppet as a puppet for correct use with volk_profile
    • Fix index_max kernels
    • Fix rotator. We hope that we finally found the root cause of the issue.
  • Kernel optimizations
    • Updated log10 calcs to use faster log2 approach
    • Optimize complexmultiplyconjugate
  • New kernels
    • accurate exp kernel is finally merged after years
    • Add 32f_s32f_add_32f kernel to perform vector + scalar float operation
