# Intrinsics for Intel® Streaming SIMD Extensions (Intel® SSE)

This section describes the C++ language-level features supporting the Intel® Streaming SIMD Extensions (Intel® SSE) in the Intel® C++ Compiler Classic. The prototypes for Intel® SSE intrinsics are in the xmmintrin.h header file.

To use these intrinsics, include the immintrin.h file as follows:

    #include <immintrin.h>

The following topics summarize these intrinsics.
