System block diagram

This is a very rough block diagram of what I'm working towards. The FPGA in the middle is what does the bulk of the grunt work, the microcontroller to the right handles SD card access, keyboard/joystick input translation, flash updates and model control logic.

As you can see, there's no much to it once you fit the bigger bits into one chip.

I have, however, cross-labelled "contended ram" and "uncontended ram" - they obviously should be the other way around. This is what happens when you try to make block diagrams quickly while tired.
