INSTRUCTION SET REFERENCE
MOVUPS—Move Unaligned Four Packed Single-FP
Description
The linear address corresponds to the address of the least-significant byte of the referenced
memory data. When a memory address is indicated, the 16 bytes of data at memory location
m128 are loaded to the 128-bit multimedia register xmm or stored from the 128-bit multimedia
register xmm. When the register-register form of this operation is used, the content of the 128-
bit source register is copied into 128-bit register xmm. No assumption is made about alignment.
