CPU Diagnostic

[Raj]

Hi ALL,

I just want to write a CPU diagnostic program.

1. What are the tests has to be implemented for minimal diagnostic?

2. Is there any chance of particular hardware part getting failed?
( Like Adder, Floating point unit, Branch Prediction Logic)

3. How to test the differnt execution units of a Superscalar processor
like Pentium?

4. Is it necessary to test all the x86 instructions supported by
the processor?

Thanks In Advance
