<listitem>

<para>In IEEE 1275 parlance, the address that a program uses to access
|
|
a memory location or
|
|
memory-mapped device register. Depending on the presence or absence of
|
|
memory mapping hardware in the system, and whether or not that mapping
|
|
hardware is enabled, a virtual address may or may not be the same as the
|
|
physical (real) address that appears on an external bus. The IEEE 1275
|
|
definition of “virtual address” corresponds to The PA's
|
|
definition of “effective address.” Except as noted, this
|
|
document uses the IEEE 1275 definition of virtual address.</para>
|
|
|
|
<para>In PA parlance, an internal address within the PA address
|
|
translation mechanism, used

as in intermediate term in the translation of an effective address to the
|
|
corresponding real address.</para>
