The Process's Logical View
In order to facilitate the concept of relocatable code, compiled programs are linked against a logical memory image map. For 32-bit narrow applications, the logical size is 2^32, or 4 GB; in the case of 64-bit wide applications, the theoretical size is limited to 2^64, or 16 exabytes! In either case, the logical map is divided into four quadrants of equal size. This is not an arbitrary configuration. It is dictated by the underlying design of the HP PA-RISC hardware platform and its virtual memory system.
We discuss the virtual memory-to-physical memory mapping in the next chapter, but first we must look at the rules and options that control the placement of a program's various memory objects into a logical space. ...
