XORPS

Bitwise Logical XOR for Single-Precision Floating-Point Values

Opcode Mnemonic Description
0F 57 /r XORPS xmm1, xmm2/m128 Bitwise exclusive-OR of xmm2/m128 and xmm1.
Description

Performs a bitwise logical exclusive-OR of the four packed single-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 destination operand is an XMM register.

Operation
Destination[0..127] = Destination[0..127] ^ Source[0..127];
