NEON overview

Applicable for STM32MP13x lines, STM32MP15x lines

Arm® NEON technology is an advanced single instruction multiple data (SIMD [1]) architecture extension for the Arm® Cortex®-A Series.

NEON technology is intended to improve the multimedia user experience by accelerating audio and video encoding/decoding, user interface, 2D/3D graphics or gaming. NEON can also accelerate signal processing algorithms and functions to speed up applications such as audio and video processing, voice and facial recognition, computer vision and deep learning [2].
