they are using the FPU heavily - in my experience an FPU design can be prone to gnarly and unpredictable bugs that are related to certain combinations of bit patterns (eg hammering all ‘1’s to all ‘0’s) in successive pipe stages which my be issued in an out of order sequence - it is very hard to diagnose and correct such failures and impossible to screen for them on a production tester
