Nothing fancy yet, just calls the serial code in a loop. I will try to folow this up with at least some of: - SSE2 version of serial code - NEON version of serial code - NEON version using vcvt.f32.f16/vcvt.f16.f32 - F16C (between AVX and AVX2) version using vcvtph2ps/vcvtps2ph The last two are fastest but need runtime detection.
