Thermal Management
A small amount of hysteresis has been included to prevent an excessive amount of
operating point transitions when the processor temperature is near its maximum
operating temperature. Once the temperature has dropped below the maximum
operating temperature and the hysteresis timer has expired, the operating frequency
and voltage transition back to the normal system operating point. This is illustrated in
.
Once a target frequency/bus ratio is resolved, the processor core will transition to the
new target automatically.
• On an upward operating point transition, the voltage transition precedes the
frequency transition.
• On a downward transition, the frequency transition precedes the voltage transition.
When transitioning to a target core operating voltage, a new VID code to the voltage
regulator is issued. The voltage regulator must support dynamic VID steps to support
this method.
During the voltage change:
• It will be necessary to transition through multiple VID steps to reach the target
operating voltage.
• Each step is 12.5 mV for compliant VRs.
• The processor continues to execute instructions. However, the processor will halt
• The processor continues to execute instructions. However, the processor will halt
instruction execution for frequency transitions.
