CPU Thermal and Power Optimization Capabilities
Control Time Window #1 values may be programmed to be within a range of 100 mS-
10 seconds. Control Time Window #2 values should be in the range 10 ms to 100 ms.
The following formula is used to calculate the Power Limit for Power Limit #1 and Power
Limit #2:
Power_Limit
= Power (in mW) / (2^ POWER_UNIT)
For example, if the Power Limit is 15 Watts, then:
Power_Limit
= (15 * 1000) / 2^3
= 1875
The following formula can be used to calculate Control Time Windows (tau), given the
following
Time Window
= (float) ( (1 + (X/4)) * (2 ^ Y) )
where X = Z[6:5] and Y = Z[4:0]
The following formula is used to calculate the Control Time Window:
where t
x
is the desired time.
For example, assume a TIMEUNIT of 10 and a desired time-window of 10 seconds:
