Abstract
A system and method for providing a microprocessor with a software accessible serial number. A plurality of programmable fuses on the processor are encoded with a value representative of a serial number. Circuitry is provided on the processor for transferring the value encoded on the programmable fuses to a machine specific or general purpose register or storage device. The machine specific or general purpose register or storage unit is software accessible.
