ADDPS (parallel) and ADDSS (scalar) add the pair of operands. SUBPS (parallel) and SUBSS (scalar) subtract the pair of operands. MULPS (parallel) and MULSS (scalar) multiply the pair of operands.DIVPS (parallel) and DIVSS (scalar) divides the pair of operands. SQRTPS…
I’m quite sure that Intel would not like to see SSE2 named 128-bit MMX. In fact, MMX has a bad reputation: the Intel marketing hype pushed it as an universal solution to multimedia requirements, but at the same time the…
PAND mm, mm/m64 PANDN mm, mm/m64 POR mm, mm/m64 PXOR mm, mm/m64 The PAND (Bitwise Logical And), PANDN (Bitwise Logical And Not), POR (Bitwise Logical OR), and PXOR (Bitwise Logical Exclusive OR) instructions perform bitwise logical operations on 64-bit quantities.…
