Overview

The Intel Intrinsics Guide is an interactive reference tool for Intel intrinsic instructions, which are C style functions that provide access to many Intel instructions – including Intel® Streaming SIMD Extensions [XX] (Intel® SSE[XX]), Intel® Advanced Vector Extensions (Intel® AVX), and more – without the need to write assembly code.

This guide provides searching and filtering functionality, in addition to reference information for every intrinsic. Reference information includes synopsis, description, functional operation, and corresponding instruction(s).

Supported Technologies

Intel® Intrinsics Guide currently includes intrinsics for the following technologies:

• MMX™
• Intel® SSE
• Intel® SSE2
