Wrong neon. > Thanks for reading, any guidance appreciated. https://developer.arm.com/technologies/neon says: ARM NEON technology is an advanced SIMD (single instruction multiple = data) architecture extension for the ARM Cortex-A series and Cortex-R52 = processors. NEON technology was introduced to the ARMv7-A and ARMv7-R profiles. It = is also now an extension to the ARMv8-A and ARMv8-R profiles. So here NEON is a subset of the instruction set. Its purpose is (again quoting that page): 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. =3D=3D=3D Mark Millard markmi at dsl-only.net
