Optimizing DirectFB with ARM NEON

DirectFB (Direct Frame Buffer) is a graphics library that is widely used in embedded systems, especially home market. More and more applications or libraries choose DirectFB as backend, such as Cairo, GDK, Qt, V8, X11 and Webkit. ARM NEON technology could be well used in 2D acceleration. In this blog, I’ll describe how to optimize DirecFB using NEON.
