Appeal No. 1997-3792
Application No. 08/321,334
Figure 6 shows a microcontroller thread which determines
whether the current clock frequency is lower than the lowest
frequency (F ) at which the CPU can operate with a reduced
rv
supply voltage and, if the answer is yes, asserts a signal
REDUCE_V in order to reduce the supply voltage to the CPU
(Spec. at 20, line 22 to p. 21, line 8).
Figure 7 shows an alternative heat management algorithm
in the form of a table in which the temperature or temperature
range being is used as an index to access values representing
the required clock frequency, supply voltage and fan setting
(Spec. at 21, lines 9-20).
B. The claims
Claims 1 and 11, the only independent claims on appeal,
read as follows:
1. A computer system comprising:
a microprocessor;
means for generating a clock signal, said means including
means responsive to a control signal for selecting a maximum
clock signal frequency value; and
means for adjusting the maximum clock signal frequency
value in accordance with idle and busy operating conditions of
the microprocessor.
11. A computer system comprising:
