The Intel

 Itanium

®

 Processor 9300 Series and Intel

®

 Itanium

®

 Processor 9500 Series 

uses a thermal sensing device called Digital Thermometer (DT) to read the values from 
the thermal sensors available on the processor die. The DT also compares these values 
to a thermal trip point that is hard-wired. Calibration information is used to translate 
the DT output to processor temperature in degrees Celsius relative to the PROCHOT 
setpoint. DT readout is available in CSR or via SMBus. When it is below the PROCHOT 
setpoint the DT readout will have a positive value. The DT has a limited range. It will 
report out the value of its upper or lower limits when it has reached the limits and set 
QR_CSR_IPF_THERM_STATUS.valid = 1’b0.

 shows the processor thermal sensor accuracy with respect to the DT readout 

for the an Intel

®

 Itanium

®

 Processor 9300 Series. The margin of error is relative to 

PROCHOT and represents the typical ±3-sigma range. This data is for a large sample of 
parts. It should be noted that a particular part should be consistent across the entire 
operating range.
