The Intel Pentium has a CPUID (processor identification) instruction. Investigate this instruction and suggest ways in which it may be used.
What will be an ideal response?
The purpose of this question is simply to make students aware of a particular instruction that does not perform
useful calculation or data processing, but simply returns data from the processor that can be used by the
operating system to determine what architectural facilities are available. This enables the operating system to
decide what hardware features need to be simulated in software.
Interestingly, an early Intel version of the Pentium family did contain a unique serial number that identified the
actual specific chip. There are, of course, lots of advantages in doing this; for example, identifying faulty
processors. However, the idea rapidly died as not everyone wanted their processor to be uniquely identified.
