NettetI tried an SSSE3 version to take advantage of PALIGNR instead of MOVSS + SHUFPS, but it wasn't as advantageous as I had hoped -- 10% faster on Core 2, but 7% slower on Atom. One reason is that PALIGNR is a shift instruction, so on Atom it still requires pipe 0, while MOVSS is a cheap instruction that can fit in a pipe 1 hole.

Nettet8. sep. 2024 · The mulss instructions are multiplying a float in an xmm register with the float stored at an address, and the movss instruction is moving a float from an xmm register into a memory location. That's x86 architecture. Your processor's manufacturer should provide documentation (e.g. Intel).
