SWIRL (Intel logo)TRADEMARK BRANDPROCESSOR NUMBERSSPEC FPO Pin Count: 1700 Package Size: 45mm x 37.5mm Processor Based on S Processor Line Chip Package LGA Top-Side Markings The EDX processor signature value after reset is equivalent to the processor signature output value in the EAX register.Ĭache and TLB descriptor parameters are provided in the EAX, EBX, ECX and EDX registers after the CPUID instruction is executed with a 2 in the EAX register.

When EAX is initialized to a value of ‘1’, the CPUID instruction returns the Extended Family, Extended Model, Processor Type, Family Code, Model Number and Stepping ID value in the EAX register.

Refer table above for the processor stepping ID number in the CPUID information.

The Stepping ID in Bits indicates the revision number of that model.

The Model Number corresponds to Bits of the EDX register after RESET, Bits of the EAX register after the CPUID instruction is executed with a 1 in the EAX register, and the model field of the Device ID register accessible through Boundary Scan.The Family Code corresponds to Bits of the EDX register after RESET, Bits of the EAX register after the CPUID instruction is executed with a 1 in the EAX register, and the generation field of the Device ID register accessible through Boundary Scan.The Extended Model, Bits in conjunction with the Model Number, specified in Bits, are used to identify the model of the processor within the processor’s family.

The Extended Family, Bits are used in conjunction with the Family Code, specified in Bits, to indicate whether the processor belongs to the Celeron ®, Pentium ®, or Intel ® Core™ processor family.
