3-56 Vol. 2A ANDPD—Bitwise Logical AND of Packed Double-Precision Floating-Point Values
INSTRUCTION SET REFERENCE, A-M
ANDPD—Bitwise Logical AND of Packed Double-Precision Floating-
Point Values
Description
Performs a bitwise logical AND of the two packed double-precision floating-point
values from the source operand (second operand) and the destination operand (first
operand), and stores the result in the destination operand.
The source operand can be an XMM register or a 128-bit memory location. The desti-
nation operand is an XMM register.
In 64-bit mode, using a REX prefix in the form of REX.R permits this instruction to
access additional registers (XMM8-XMM15).
Operation
DEST[127:0] ← DEST[127:0] BitwiseAND SRC[127:0];
Intel C/C++ Compiler Intrinsic Equivalent
ANDPD __m128d _mm_and_pd(__m128d a, __m128d b)
SIMD Floating-Point Exceptions
None.
Protected Mode Exceptions
#GP(0) For an illegal memory operand effective address in the CS, DS,
ES, FS or GS segments.
If a memory operand is not aligned on a 16-byte boundary,
regardless of segment.
#SS(0) For an illegal address in the SS segment.
#PF(fault-code) For a page fault.
#NM If CR0.TS[bit 3] = 1.
#UD If CR0.EM[bit 2] = 1.
If CR4.OSFXSR[bit 9] = 0.
If CPUID.01H:EDX.SSE2[bit 26] = 0.
If the LOCK prefix is used.
