# 1.27.0[−][src]Function core::arch::x86_64::_mm_madd_epi16

    pub unsafe fn _mm_madd_epi16(a: __m128i, b: __m128i) -> __m128i

This is supported on x86-64 and target feature `sse2` only.

Multiplies and then horizontally add signed 16 bit integers in `a` and `b`.

Multiplies packed signed 16-bit integers in `a` and `b`, producing intermediate signed 32-bit integers. Horizontally add adjacent pairs of intermediate 32-bit integers.
