The Intel® Advanced Vector Extensions (Intel® AVX) intrinsics are assembly-coded functions that call on Intel® AVX instructions, which are new vector SIMD instruction extensions for the IA-32 and Intel® 64 architectures. The Intel® Advanced Vector Extensions are architecturally similar to the Intel® Streaming SIMD Extensions (Intel® SSE) and double-precision floating-point portions of Intel® SSE2.
The prototypes for the Intel® AVX intrinsics are available in the gmmintrin.h file.
The Intel® AVX intrinsics are supported on the IA-32 and Intel® 64 architectures built from 32nm process technology. They map directly to the Intel® AVX new instructions and other enhanced 128-bit SIMD instructions.
