I'm student in electrical engineering and write my thesis on some topic of the e&e compartment. The main focus is on the computers of the A320 flightcraft, actually called E&E Compartment. Sadly because of closed source of this avionics part there is no general information of what it is. This is also clear why, most infos can only accessed by technician because of several security reasons. But maybe there is still some general descriptions and pictures that shows for example the location of e&e and text like: e&e has distributed system architecture where each computer has specific role, they are all connected by arinc... blabla.. and similiar and so on :)
It can be all, books, patents, googling keywords.. It would all help!
