Streaming SIMD Extensions 2 Intrinsics Implementation

The Pentium® 4 processor is the only Intel processor that supports Streaming SIMD Extensions 2 (SSE2) intrinsics.

On processors that do not support SSE2 instructions but do support MMX Technology, you can use the sse2mmx.h emulation pack to enable support for SSE2 instructions. You can use the sse2mmx.h header file for the following processors:

• Itanium® Processor

• Pentium® III Processor

• Pentium® II Processor

• Pentium® with MMX™ Technology
