Looking for Resource for Architecture Description

I’m writing my thesis and I need a quotable resource for a technical description of the CUDA architecture.
I’ve looked through both CUDA by Example and Programming Massively Parallel Processors and can’t find what I’m looking for.

Have you looked at Chapters 1 and 2 of the CUDA C Programming Guide? That’s the standard high-level reference on the CUDA architecture.

I had not looked at the Programing Guide in almost a year. I think it’s exactly what I need.

Thanks for your help.
