MOVAPD
In the x86 assembly programming language, MOVAPD is the name for a specific action performable by modern x86 processors with 2nd-generation Streaming SIMD Extensions (SSE2). This action involves copying a pair of numbers to temporary space in the processor for use in other computations. MOVAPD is one of the fastest ways to accomplish this effect. Specifically, MOVAPD causes a 16-byte-aligned packed-doubles source to be copied to an XMM register or a 16-byte memory region. ==Usage==
The source operand can be either an XMM register (''xmm2'') or a memory address (''m128''). The destination operand can be either an XMM register (''xmm1'') or a memory address (''m128''). Note, however, that the source and destination operands cannot both be memory addresses.
