Features and Benefits
The Neon technology is a packed SIMD architecture that supports multiple data types. Implementation on Neon technology also supports multiple instructions in parallel.
Neon can be used in multiple ways, including Neon-enabled libraries, auto-vectorization in compiler, Neon Intrinsics, and Neon assembly code.
A wide range of codecs and DSP modules are available from several Arm partners in the Neon ecosystem.
One of the easiest ways to take advantage of Neon is with an open source library that already utilizes Neon.
Neon Intrinsics Search Engine
Neon Intrinsics are function calls that the compiler replaces with an appropriate Neon instruction or sequence of Neon instructions. This search engine allows you to look up Intrinsic calls that provide almost as much control as writing assembly language, but leave the allocation of registers to the compiler, so developers can focus on the algorithms.
