GPU-based X server on top of EGL and openVG

Based on GUI desktop environment, running PC-class applications with rich user experience has become popular in mobile devices. A window system is an essential component of GUI desktop. As a window system for mobile devices, we implemented X server on top of EGL and OpenVG. GPU-based X server described in this paper may serve as a standard model of a window system in future mobile devices because graphics operations can be accelerated with less power consumption.
