NEON are specialized processor instructions that can handle several operations at once, for example, 8 additions of 8 bytes to 8 other bytes. They are very useful for image processing. NEON instructions are supported both by the JeVois hardware platform and by the JeVois programming framework. In fact, one can directly call NEON instructions using C-like function calls and specialized C data types to represent small vectors of numbers (like 8 bytes). This demo uses a blur filter from the open-source NE10 library.
