# Function core::arch::x86_64::_mm_gf2p8mul_epi8[−][src]

    pub unsafe fn _mm_gf2p8mul_epi8(a: __m128i, b: __m128i) -> __m128i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512gfni,avx512bw,avx512vl` only.

Performs a multiplication in GF(2^8) on the packed bytes. The field is in polynomial representation with the reduction polynomial x^8 + x^4 + x^3 + x + 1.
