Overview: Streaming SIMD Extensions 3

The Intel® C++ intrinsics listed in this section are designed for the Intel® Pentium® 4 processor with Streaming SIMD Extensions 3 (SSE3). They will not function correctly on other IA-32 processors. New SSE3 intrinsics include:

• Floating-point Vector Intrinsics
• Integer Vector Intrinsics
• Miscellaneous Intrinsics
• Macro Functions

The prototypes for these intrinsics are in the pmmintrin.h header file.

Note

You can also use the single ia32intrin.h header file for any IA-32 intrinsics.
