13 As of the MIPS32 and MIPS64 specs from MTI, the PRId register (CP0
14 register 15, select 0) is defined in this (backwards compatible) way:
16 +----------------+----------------+----------------+----------------+
17 | Company Options| Company ID | Processor ID | Revision |
18 +----------------+----------------+----------------+----------------+
19 31 24 23 16 15 8 7
21 I don't have docs for all the previous processors, but my impression is
22 that bits 16-23 have been 0 for all MIPS processors before the MIPS32/64
23 spec.
