C.2 Intel
®
Quark SoC X1000 Stepping
The Intel
®
Quark SoC X1000 stepping is identified by both:
• Processor ‘Family/Model/Stepping’ returned by the CPUID instruction. This will
always return 0x590 for Intel
®
Quark SoC X1000.
• Revision ID register of the Host Bridge, located at D0:F0. Reads of the register will
reflect the stepping.
