Well you can apply it to any pair of (adjacent) levels of the memory hierarchy. But the main problem with the square root model is that it only models random access time, but not when they are incurred and when data is already in cache. (There are also 2-3 levels of caches, no architecture that I’m aware of has more than 3, maybe 4 if you count the CPU registers but their allocation is usually fixed at compile time) |
