Hm... you have to elaborate on that one. Aren't those caches like other 
caches, too? With well known algorithms like LRU?

Simulating branch prediction seems more complex to me (probably because 
I'm thinking x86, not ARM).

What to others think about the network and hard disk simulation I've
mention in my previous post?
