Architected System Memory Map for PowerPC 32-bit and 64-bit Systems

      Memory Map - The System Memory Map in the PowerPC* (32/64 bit)
system architecture consists of n GB of real memory and can be shown
on the left of the Fig.

      The Architected System Memory Space which is located in the
upper 16 MB of the overall System Memory Map is expanded on the right
of the figure below.  Note that, for simplicity, the resolution of
this figure is 1 MB.

      Architected System Memory Map - The Table contains more details
regarding the layout, the descriptions, and the specific ranges of
addresses in the 16 MB of Architected System Memory Space.  All items
identified as "Architected" must be supported by all RISC/6000*
products unless specifically identified as optional under the details
regarding the specific facility.
