Register Set
Note that the PowerPC architecture defines this register in more general terms
than defined in Table 2-1. Architecturally, the PVR consists of two 16-bit
fields as described in Table 2-2.
Implementation Note
—The G2 core version number is 0x8081 and the
revision level starts at 0x1010 and changes for each revision of the core. The
G2_LE core version number is 0x8082 and the revision level starts at 0x2010
and changes for each revision of the core. Table 2-3 describes some of the
PVR values for G2-related devices.
10–15
PID
1
Processor identification. This field is used to indicate different implementations of the PowerPC
architecture.
16–19
PROC
Process revision. This field identifies the relative process changes and revisions.
20–23
MFG
Manufacturing revision. This optional field identifies relative manufacturing revisions and changes.
This was formerly the major processor design revision indicator (in the MPC603e).
24–27
MJREV
Major processor design revision indicator
28–31
MNREV
Minor processor design revision indicator
1
The PID values are assigned by the PowerPC architecture group.

0–15
Version
A 16-bit number that uniquely identifies a particular processor version. This number can be used
to determine the version of a processor; it may not distinguish between different end product
models if more than one model uses the same processor.
16–31
Revision
A 16-bit number that distinguishes between various releases of a particular version (that is, an
engineering change level). The value of the revision portion of the PVR is implementation-specific.
The processor revision level is changed for each revision of the device.
