Fri Oct 4 10:20:48 UTC 2024

There is already an intrinsic for SHA-3 for aarch64, which gives significant speed improvement on that architecture, so this pull request is bringing similar improvement for tha x64 family of systems that have the AVX-512 extension. Rudimentary measurements show that 30-40% speed improvement can be achieved.
