Further thoughts on the simulation task

Lying in bed this morning and puzzling over what to do …

At first I thought what I should do is copy one of the existing operating system models for NoCs, but that simply would not be flexible enough.

What I have to do is model the hardware (including the modifications to the MMU I want to see) as, essentially, some form of black box, and build other layers – including the memory tree – above that. That means I need to separate the CPU/tiles from global memory: sounds simple in theory but implementing this is going to be very far from easy.
