 String cpuName,
 String cpuFamily,
 String cpuModel,
 String cpuStepping,
 String processorID,
 boolean cpu64bit,
 long vendorFreq)

Method Details

getVendor

public String getVendor()

Processor vendor.

Returns:

vendor string.

getName

public String getName()

Name, eg. Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz

Returns:

Processor name.

getFamily

public String getFamily()

Gets the family. For non-Intel/AMD processors, returns the comparable value, such as the Architecture.

Returns:

the family

getModel

public String getModel()

Gets the model. For non-Intel/AMD processors, returns the comparable value, such as the Partnum.

Returns:

the model

getStepping

public String getStepping()

Gets the stepping. For non-Intel/AMD processors, returns the comparable value, such as the rnpn composite of Variant and Revision.

Returns:

the stepping

getProcessorID

public String getProcessorID()

Gets the Processor ID. This is a hexidecimal string representing an 8-byte value, normally obtained using the CPUID opcode with the EAX register set to 1. The first four bytes are the resulting contents of the EAX register, which is the Processor signature, represented in human-readable form by getIdentifier() . The remaining four bytes are the contents of the EDX register, containing feature flags.

For processors that do not support the CPUID opcode this field is populated with a comparable hex string. For example, ARM Processors will fill the first 32 bytes with the MIDR. AIX PowerPC Processors will return the machine ID.

NOTE: The order of returned bytes is platform and software dependent. Values may be in either Big Endian or Little Endian order.

NOTE: If OSHI is unable to determine the ProcessorID from native sources, it will attempt to reconstruct one from available information in the processor identifier.

Returns:

A string representing the Processor ID

getIdentifier

public String getIdentifier()

Identifier, eg. x86 Family 6 Model 15 Stepping 10. For non-Intel/AMD processors, this string is populated with comparable values.

Returns:

Processor identifier.

isCpu64bit

public boolean isCpu64bit()

Is CPU 64bit?

Returns:

True if cpu is 64bit.

getVendorFreq

public long getVendorFreq()

Vendor frequency (in Hz), eg. for processor named Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz the vendor frequency is 2000000000.

Returns:

Processor frequency or -1 if unknown.

getMicroarchitecture

public String getMicroarchitecture()

Returns the processor's microarchitecture, if known.

Returns:

A string containing the microarchitecture if known. Constants.UNKNOWN otherwise.

toString

public String toString()

Overrides:

toString in class Object
