CIM_Processor

Subclass of CIM_LogicalDevice

Capabilities and management of the Processor LogicalDevice.

Local properties

uint16 LoadPercentage

Loading of this Processor, averaged over the last minute, in Percent.

uint32 ExternalBusClockSpeed

The speed (in MHz) of the external bus interface (also known as the front side bus).

uint32 MaxClockSpeed

The maximum speed (in MHz) of this Processor.

string UniqueID

A globally unique identifier for the Processor. This identifier can be unique only within a Processor Family.

uint16 AddressWidth

Processor address width in bits.

uint32 CurrentClockSpeed

The current speed (in MHz) of this Processor.

string Stepping

Stepping is a free-form string that indicates the revision level of the Processor within the Processor.Family.

uint16 DataWidth

Processor data width in bits.

uint16 NumberOfEnabledCores

Number of processor cores enabled for processor.

string OtherFamilyDescription

A string that describes the Processor Family type. It is used when the Family property is set to 1 (“Other”). This string should be set to NULL when the Family property is any value other than 1.

uint16 Family

The Processor family type. For example, values include “Pentium(R) processor with MMX(TM) technology” (value=14) and “68040” (value=96).

uint16[] Characteristics

Array of enumerated values that describes the characteristics of the processor. The characteristics include certain features of the processor such as 64 bit support for data width of the processor. Note that if this property does not contain the value corresponding to a feature of the processor, than the feature either is not that some of the features of the processor may exist but may not be enabled. To find the the currently enabled features the processor, reffer to the EnabledProcessorCharacteristics property. Values specified in the enumeration may be obtained from SMBIOS v2.5 Type 4 offset 26h (Processor Characteristics Word). 32-bit Capable - describes whether the processor has the capability for 32 bits data width. 64-bit Capable - describes whether the processor has the capability for 64 bits data width. Enhanced Virtualization - describes whether the processor has the capability for executing enhanced virtualization instructions. Hardware Thread - indicates that the processor is capable of the hardware threading. NX-bit - describes whether the processor has capability to utilize non-execute bit and can differentiate the memory marked strictly for storage. Power/Performance Control - describes whether the processor has capability for load based power savings. Core Frequency Boosting - describes whether the processor has a capability for one processor core to increase its frequency whenever the other core has gone into an idle state.

uint16[] EnabledProcessorCharacteristics

This property indicates the enabled states of the corresponding processor characteristics. The property array is indexed with ProcessorCharacteristics property array of the associated CIM_ProcessorCapabilities instance through the CIM_ElementCapabilities association. Each of the values in the ProcessorCharacteristics array property shall have its enabled state indicated in the corresponding element of this property array. For example; if the ProcessorCharacteristics array has value - NX-bit - for the first element of the array, then the first element of this property will contain the value for the enabled state of the NX-bit feature of the processor: whether the processor currently differentiates the dedicated storage memory based on the non-execute bit. Unknown - the processor feature is in unknown state. Enabled - the processor feature is enabled and could be used. Disabled - the processor feature is disabled and cannot be used. Not Applicable - the processor feature does not have state context.

string Role

A free-form string that describes the role of the Processor, for example, “Central Processor” or “Math Processor”.

uint16 CPUStatus

The CPUStatus property that indicates the current status of the Processor. For example, the Processor might be disabled by the user (value=2), or disabled due to a POST error (value=3). Information in this property can be obtained from SMBIOS, the Type 4 structure, and the Status attribute.
