Appeal No. 1997-3792
Application No. 08/321,334
The Figure 5 embodiment is responsive to a temperature
monitor 501 rather than a status line.
In each of the foregoing embodiments, the output trigger
signal generated in response to the counter determines (i.e.,
selects) whether the CPU clock will be changed to the lower
speed or permitted to continue operatm 1's requirement for
"means . . . for selecting a maximum clock ion at the higher
speed. Thus, each embodiment satisfies claisignal frequency
value" (emphasis aded). More particularly, in the embodiments
of Figures 1, 2a-2b, and 4 the CPU speed is selected in
response to status signals not representing temperature,
whereas in the Figure 5 embodiment the CPU speed is selected
in response to temperature. However, none of these
embodiments includes apparatus satisfying claim 1's additional
requirement for "means for adjusting the maximum clock signal
frequency value in accordance with . . . operating conditions
of the microprocessor" (emphasis added). The examiner's
position appears to be that this limitation reads on the same
circuitry that performs the selection function, i.e., the
circuitry which determines whether the clock should be slowed
or permitted to continue to run at high speed. We do not
