x86 Instruction Set Reference

Performs an SIMD computation of the square roots of the four packed single-precision floatingpoint values in the source operand (second operand) stores the packed single-precision floatingpoint results 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. See Figure 10-5 in the IA-32 Intel Architecture Software Developer's Manual, Volume 1 for an illustration of an SIMD single-precision floating-point operation.

Destination[0..31] = SquareRoot(Source[0..31]);
Destination[32..63] = SquareRoot(Source[32..63]);
Destination[64..95] = SquareRoot(Source[64..95]);
Destination[96..127] = SquareRoot(Source[96..127]);
