In computing, EXA is a graphics acceleration architecture of the X.Org Server (see also X Window System) designed to replace XAA (the XFree86 Acceleration Architecture) and to make the XRender extension more usable, with only minor changes needed to adapt obsolete XFree86 video drivers written to use XAA; it was designed by Zack Rusin and announced at LinuxTag 2005 and first released with X.Org Server version 6.9/7.0.
