ARM Architecture and programming

This article records some of the books that read "ARM architecture and programming".

Personally, when learning arm system, do not need to memorize, as long as some key to the general memory, such as ARM Register (General Register, PC, LR, SP, CPSR, SPSR), ARM interrupt processing system, commonly used arm assembly instructions.

This article is basically from the book, are some of the key knowledge, need we often go to review.
