Description: API documentation for the Rust `__msa_dotp_s_d` fn in crate `core`.
Keywords: rust, rustlang, rust-lang, __msa_dotp_s_d

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

    pub unsafe fn __msa_dotp_s_d(a: v4i32, b: v4i32) -> v2i64

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

Vector Signed Dot Product

The signed integer elements in vector `a` (four signed 32-bit integer numbers) are multiplied by signed integer elements in vector `b` (four signed 32-bit integer numbers) producing a result the size of the input operands. The multiplication results of adjacent odd/even elements are added and stored to the destination vector (two signed 64-bit integer numbers).
