Function core_arch::mips::__msa_dotp_s_d

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

🔬 This is a nightly-only experimental API. (stdsimd)

This is supported on MIPS 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 resultsof adjacent odd/even elements are added and stored to the destination vector (two signed 64-bit integer numbers).
