Function core_arch::mips::__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)

This is supported on MIPS 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).
