🔬This is a nightly-only experimental API. (
Available on (x86 or x86-64) and target feature
avx512vnniand x86-64 only.
Multiply groups of 2 adjacent pairs of signed 16-bit integers in a with corresponding 16-bit integers in b, producing 2 intermediate signed 32-bit results. Sum these 2 results with the corresponding 32-bit integer in src using signed saturation, and store the packed 32-bit results in dst.
