Appeal No. 1999-0288
Application No. 08/538,071 Page 9
Wibecan does not specifically state the at [sic; that] this bit
it [sic; is] in a machine state register, it would have been
obvious to one of ordinary skill in the art to realize that the
enablement of a processing system to recognize which mode or
process it is operating in, such as user or supervisor mode, are
usually located in a register which is accessible to the
processing systems other elements.” The examiner additionally
repeats the argument from claim 6 that the modification would
have been obvious because it would ensure that the specific
process, along with the events associated with the process, are
identified correctly, in order to enable the counters correctly
for performance monitoring of the events and processes.
With respect to the lack of a teaching or suggestion of a
second MMCR in Wibecan and Brantley, the examiner argues (final
rejection, pages 7 and 8) that:
It would have been obvious to one of ordinary
skill in the art to allow the combined system
of Wibecan and Brantley to include the use of
multiple ones of control registers because it
would enable the system the incorporate the
versatility of controlling a plurality of
counters with these control registers, thus
allowing the adjustment and “control” of these
registers to be altered more readily by the system.
