WebWe will use the NEON Intrinsics API to program the NEON Units in our cores. An intrinsic behaves syntactically like a function, but the compiler translates it to a specific instruction that is inlined in the code. In the following sections, we will guide you through reading the NEON Programmer’s guide and learning to use these APIs. WebJan 8, 2013 · Intrinsics Intrinsics are functions which are separately handled by the compiler. These functions are often optimized to perform in the most efficient ways possible and hence run faster than normal implementations. However, since these functions depend on the compiler, it makes it difficult to write portable applications.
