Arithmetic/Logic Instructions<br />
• Arithmetic/Logic instruction(ADD, SUB, RSB,<br />
ADC, SBC, RSC, AND, BIC, EOR, ORR 등)은 2개<br />
의 source operand와 1개의 destination<br />
operand를 가진다.<br />
– Source operand 중 하나는 register이고 나머지 하나<br />
는 (shifted) immediate value이든지 (shifted) register<br />
이다.<br />
– Destination operand는 항상 register이다.<br />
참고: <strong>ARM</strong>은 shift 전용 instruction은 없음. PC에<br />
계산 결과 값을 저장하면 jump가 일어남.<br />
