About the ARM architecture

2.1 About the ARM architecture

The ARM architecture is a load-store architecture, with a 32-bit addressing range.

ARM processors are typical of RISC processors in that only load and store instructions can access memory. Data processing instructions operate on register contents only.
It is assumed that you are using a processor that implements the ARMv4 or later architecture. All these processors have a 32-bit addressing range.
