Explanation:
Detailed explanation-1: -The ARM architecture Application level memory model uses a single, flat address space of 232 8-bit bytes, covering 4GBytes.
Detailed explanation-2: -ARM processors normally have a 32-bit address bus.
Detailed explanation-3: -The ARMv7-M architecture uses a single, flat address space of 232 8-bit bytes. Byte addresses are treated as unsigned numbers, running from 0 to 232-1. This address space is regarded as consisting of 230 32-bit words, each of whose addresses is word-aligned, meaning that the address is divisible by 4.
Detailed explanation-4: -ARM instructions are all 32 bit long are all 32-bit long (except for Thumb mode) Thumb mode). There are 232 possible machine instructions.
