ARM Instruction Format

The basic format of ARM instruction is

<opcode> (<cond>) (S) <Rd> <Rn>, (<Op2>)

Explanations of fields:

1. <opcode> is the operation code (or mnemonic symbol).
2. <cond> is the condition field, the instruction will only be executed if the condition is true.

Eight addressing approaches are supported in ARM
