+ * @file
+ * PortProxy Object Declaration.
+ *
+ * Port proxies are used when non-structural entities need access to
+ * the memory system (or structural entities that want to peak into
+ * the memory system without making a real memory access).
+ *
+ * Proxy objects replace the previous FunctionalPort, TranslatingPort
+ * and VirtualPort objects, which provided the same functionality as
+ * the proxies, but were instances of ports not corresponding to real
+ * structural ports of the simulated system. Via the port proxies all
+ * the accesses go through an actual port (either the system port,
+ * e.g. for processes or initialisation, or a the data port of the
+ * CPU, e.g. for threads) and thus are transparent to a potentially
+ * distributed memory and automatically adhere to the memory map of
+ * the system.
