|
* TranslatingPortProxy Object Declaration for FS.
|
|
|
|
*
|
|
|
|
* Port proxies are used when non structural entities need access to
|
|
|
|
* the memory system. 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 and thus are transparent to a potentially
|
|
|
|
* distributed memory and automatically adhere to the memory map of
|
|
|
|
* the system.
