ORPS<br />

Logical <strong>Bit</strong>wise OR<br />

Packed Single-Precision Floating-Point<br />

Performs a bitwise logical OR of the four packed single-precision floating-point values<br />

in the first source operand and the corresponding four packed single-precision<br />

floating-point values in the second source operand and writes the result in the<br />

destination (first source). The first source/destination operand is an XMM register.<br />

The second source operand is another XMM register or 128-bit memory location.<br />

Mnemonic Opcode Description<br />

ORPS xmm1, xmm2/mem128 0F 56 /r Performs bitwise logical OR of four packed single-precision floatingpoint<br />

values in an XMM register and in another XMM register or 128-bit<br />

memory location and writes the result in the destination XMM register.<br />
