with VOLK 2.2.0, we introduced another AVX rotator bug which is fixed with this release.
In the process 2 more bugs were identified and fixed. Further, we saw some documentation improvements.

Contributors

Changes

  • Fix loop bound in AVX rotator
  • Fix out-of-bounds read in AVX2 square dist kernel
  • Fix length checks in AVX2 index max kernels

Release v2.2.0

Hi everyone,

we have a new VOLK release v2.2.0!

We want to thank all contributors. This release wouldn't have been possible without them.

We're curious about VOLK users. Especially we'd like to learn about VOLK users who use VOLK outside GNU Radio.

If you have ideas for VOLK enhancements, let us know. Start with an issue to discuss your idea. We'll be happy to see new features get merged into VOLK.

The v2.1.0 release was rather large because we had a lot of backlog. We aim for more incremental releases in order to get new features out there.

Highlights

VOLK v2.2.0 updates our build tools and adds support functionality to make it easier to use VOLK in your projects.

  • Dropped Python 2 build support
    • Removed Python six module dependency
  • Use C11 aligned_alloc whenever possible
    • MacOS posix_memalign fall-back
    • MSVC _aligned_malloc fall-back
  • Add VOLK version in volk_version.h (included in volk.h)
  • Improved CMake code
  • Improved code with lots of refactoring and performance tweaks
