[Q] Help for Assignment on OnePlus One ! topic

Hello !
I need help for my assignment, we were asked to choose a mobile computer to study on. And we chose the ever so great OnePlus One.
What I'm asking here is just a little help to get details on the OnePlus One specifically of the following:

i) General Architecture
ii) Instruction Set and Registers
iii) Memory architecture/model
iv) Implementation issues (pipeline, coprocessors, interoperability,… etc)
v) I/O specifications (Communications, Expansions buses/cards,… etc)

It's been awhile since I've visted xda developers, but I believe you guys could help me to get information on these criterias.
If there's anything that you want to PM me, feel free to do so.
Thank You.
