In the X Window System, in the X.Org Server, EXA is a graphics acceleration architecture to make the XRender extension more usable, with only minor changes needed to adapt XFree86 video drivers written to use XAA (the XFree86 Acceleration Architecture). It was designed by Zack Rusin, announced at LinuxTag 2005 [1] and first released with X.Org Server version 6.9/7.0. KDE 3. ...

LinuxTag (or more formally ) is a Free Software expo held every summer in the town of Karlsruhe in southern Germany. ...


EXA is designed to replace XAA, which does not accelerate many 2D operations heavily used in current applications, and in particular was considered not to do enough in accelerating XRender. EXA is considered a stopgap measure to improve X.Org Server performance before the server is moved entirely to OpenGL. OpenGL (Open Graphics Library) is a specification defining a cross-language cross-platform API for writing applications that produce 3D computer graphics (and 2D computer graphics as well). ...


EXA was adapted from KAA, the Kdrive Acceleration Architecture, from the experimental Freedesktop.org Xserver. Per the initial mailing list announcement, the goals are: freedesktop. ... Xserver is an implementation of an X Window System server being developed by Keith Packard Unlike the X.Org Server, Xserver is not based on XFree86 code. ...

  1. Properly accelerate XRender;
  2. Be as simple as possible.

Many XAA drivers have had EXA support added for X11R6.9/7.0. Making this transition as easy as possible was an important design consideration [2]. Xrender (aka X Rendering Extension) introduces digital image composition as the foundation of a new rendering model within the X Window System. ...


Acronym

According to the XorgGlossary [3], EXA is an "acceleration architecture with no well-defined acronym." Dot.kde.org called it "Eyecandy Acceleration Architecture" [4]. The driver modification guide [5] calls it "EXcellent Architecture or Ex-kaa aXeleration Architecture or whatever."

This particular Exa came with a 50mm Tessar lens of early Fifties and with a prism finder, both parts of the original outfit.
Exa Ia is a member of the Exa I line, with a body construction different from the original Exa.
The Exa II line was introduced earlier than Exa I, in 1959, and manufactured concurrently with first Exa, and then Exa I models until 1963, to be replaced with Exa IIa and later, IIb.
