5.1.2

Thermal Diode Offset

In order to improve the accuracy of diode based temperature measurements, a

temperature offset value (specified as T

offset

) is programmed into a Intel

Celeron

Processor 1.66 GHz/1.83 GHz Model Specific Register (MSR) which contains thermal

diode characterization data. During manufacturing, the processor thermal diode is

evaluated for its behavior relative to a theoretical diode. Using the equation above, the

temperature error created by the difference between n

trim

and the actual ideality of the

particular processor is calculated.

If the n

trim

value used to calculate T

offset

differs from the n

trim

value used in a

temperature sensing device, the T

error(nf)

may not be accurate. If desired, the T

offset

can be adjusted by calculating n

actual

and then recalculating the offset using the actual

trim

as defined in the temperature sensor manufacturers' datasheet.

The n

trim

used to calculate the Diode Correction Toffset are listed in

Table 19

Intel

Thermal Monitor

The Intel Thermal Monitor helps control the processor temperature by activating the

TCC (Thermal Control Circuit) when the processor silicon reaches its maximum junction

temperature. The temperature at which the Intel Thermal Monitor activates the TCC is

not user configurable. Bus traffic is snooped in the normal manner, and interrupt

requests are latched (and serviced during the time that the clocks are on) while the

TCC is active.

A thermal solution that is significantly under designed may not be capable of cooling

the processor even when the TCC is active continuously.

The Intel Thermal Monitor controls the processor temperature by modulating (starting

and stopping) the processor core clocks when the processor silicon reaches its

maximum operating temperature. The Intel Thermal Monitor uses two modes to

activate the TCC: Automatic mode and on-demand mode. If both modes are activated,

Automatic mode takes precedence.

Note:

The Intel thermal monitor automatic mode must be enabled through BIOS for the

processor to be operating within specifications.

There are two automatic modes called Intel Thermal Monitor 1 (TM1) and Intel Thermal

Monitor 2 (TM2). After Automatic mode is enabled, the TCC activates only when the

internal die temperature reaches the maximum allowed value for operation.

TM1 and TM2 can co-exist within the processor. If both TM1 and TM2 bits are enabled in

the auto-throttle MSR, TM2 takes precedence over TM1. However, if TM2 is not

sufficient to cool the processor below the maximum operating temperature, then TM1

also activates to help cool down the processor.

Note:

Intel recommends

both

Thermal Monitor 1 (TM1) and Thermal Monitor 2 (TM2) be

always enabled on Intel

Celeron

Processor 1.66 GHz/1.83 GHz.
