+\subsection*{CORBA}
+
+CORBA is a middleware, which allows RPC\footnote{Remote Procedure
+  Call}-based IPC\footnote{Inter Process Communication} between
+different operating systems and different programming languages
+(Figure \ref{img:orb}).
+
+The communication interfaces are defined in IDL\footnote{Interface Definition
+  Language}. The IDL files are compiled into, e.g. c++, java, \dots,
+code which does the (de)serialization of the datatypes. The interface
+implementations (CORBA objects) are registered with language
+specific ORB\footnote{Object Request Broker}s. Each CORBA process owns
+one ORB, which handles the function requests and returns the
+calculated values.

+\end{figure}
+
+As shown in figure \ref{img:rtorb}, a real-time capable ORB extends a standard 
+ORB with the following features: locating objects in constant time,
+preallocation of resources, operating system independent priority
+handling, priority based scheduling.
+
+ACE is an open-source c++ framework for platform-independent system-
+and network-programming. TAO is a Real-time CORBA implementation build
+on top of ACE (Figure \ref{img:ace}).

+\label{img:ace}
+\end{figure}
+
+The ACE/TAO package is available for all important operating
+systems. The framework can be trimmed for embedded systems: Each
+application described in this paper consumes less than 1 MByte of
+RAM. Also the consumed CPU time is suprisingly low.
