Overview: Streaming SIMD Extensions

This section describes the C++ language-level features supporting the Streaming SIMD Extensions (SSE) in the Intel® C++ Compiler. These topics explain the following features of the intrinsics:

• Floating Point Intrinsics
• Arithmetic Operation Intrinsics
• Logical Operation Intrinsics
• Comparison Intrinsics
• Conversion Intrinsics
• Load Operations
• Set Operations
• Store Operations
• Cacheability Support
• Integer Intrinsics
• Intrinsics to Read and Write Registers
• Miscellaneous Intrinsics
• Using Streaming SIMD Extensions on Itanium® Architecture

The prototypes for SSE intrinsics are in the xmmintrin.h header file.

Note

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