I mean, yes, but I'm not sure I see your point. The Harvard vs Von Neumann architectural difference is more related to the number of AHB ports on the core.

I wouldn't confuse instruction caches with Harvard vs Von Neumann either - loads of Von Neumann machines have instruction or Flash caches too.

It's also not uncommon to run into Von Neumann cores in mobile and PC chips, just as peripheral co-processors.

It is just middle aged guy who did this stuff for years...
