Function core::arch::x86::_mm_dpbusds_epi32 [−][src]
pub unsafe fn _mm_dpbusds_epi32(src: __m128i, a: __m128i, b: __m128i) -> __m128i
This is supported on x86 and target feature
avx512vnni,avx512vl only.Expand description
Multiply groups of 4 adjacent pairs of unsigned 8-bit integers in a with corresponding signed 8-bit integers in b, producing 4 intermediate signed 16-bit results. Sum these 4 results with the corresponding 32-bit integer in src using signed saturation, and store the packed 32-bit results in dst.
