There is mysterious ‘undocumented technology’ hidden on Intel computer chips

You're barking up the wrong tree though, being able to, for instance, analyze the wear of electromigration from trackpad controllers in an attempt to determine the most common branches, is a far cry from what this likely does.

That said, I would not be surprised if part of the function of this chip is to in part prevent the above issue from happening so easily. It's likely quite complicated and would have no place on a lot of smaller single purpose controllers.

Back when we used to upgrade computers (before the intel malaise), we would "torture" the old one by letting it generate random numbers until it failed. The last "interesting" processor we tortured was a dual core AMD of some sort. After that it simply started taking too long
