ARM Processor Documentation

ARM's documentation set can be found at http://infocenter.arm.com/. Below are listed direct links to some of the more useful documents.

Each processor implements a specific version of the ARM Architecture, which covers things like the actual instruction set available. This is detailed in the appropriate ARM Architecture Reference Manual.

For more information on ARM Architectures, see: http://www.arm.com/products/processors/technologies/instruction-set-architectures.php

The actual implementation of the Architecture in hardware for a particular processor, including things like instruction timings, is then covered in the appropriate Technical Reference Manual.
