🔬This is a nightly-only experimental API. (
Available on (x86 or x86-64) and target feature
avx512bw,avx512vland x86-64 only.
Multiply packed unsigned 8-bit integers in a by packed signed 8-bit integers in b, producing intermediate signed 16-bit integers. Horizontally add adjacent pairs of intermediate signed 16-bit integers, and pack the saturated results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
