Detailed Description

This object is a proxy for a structural port, to be used for debug accesses.

This proxy object is used when non structural entities (e.g. thread contexts, object file loaders) need access to the memory system. It calls the corresponding functions on the underlying structural port, and provides templatized convenience access functions.

The addresses are interpreted as physical addresses.
