# [−][src]Function core::arch::mips64::__msa_dpadd_s_w

    pub unsafe fn __msa_dpadd_s_w(a: v4i32, b: v8i16, c: v8i16) -> v4i32

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on MIPS-64 and target feature `msa` only.

Vector Signed Dot Product and Add

The signed integer elements in vector `b` (eight signed 16-bit integer numbers) are multiplied by signed integer elements in vector `c` (eight signed 16-bit integer numbers) producing a result twice the size of the input operands. The multiplication results of adjacent odd/even elements are added to the vector `a` (four signed 32-bit integer numbers).
