- 1. ADDRESSING MODES Mr. C.KARTHIKEYAN, ASSISTANT PROFESSOR, ECE , RMKCET
- 2. MIPS ADDRESSING MODES Immediate Addressing Mode Register Addressing Mode Base or Displacement Addressing Mode PC-Relative Addressing Mode Pseudo Direct Addressing Mode
- 3. Immediate Addressing Mode Eg:1. addi $s0, $zero,7 Eg:4. ori $t0,$t1,8 $s0 = 0 + 7 $t0 = $t1 | 8
- 4. Register Addressing Mode Eg:1. add $s1,$s2,$s3 Eg:2. or $t0,$t1,$t2 Eg:3. srl $s7,$s0,4 $s1 = $s2 + $s3 $t0 = $t1 | $t2 $s7 = $s0 >> 4
- 5. Base / Displacement Addressing Mode Eg:1. lw $s1, 4($s2) Eg:2. sw $s0, 8($s4) $s1 = Mem [$s2+4] Mem [$s4+8] = $s0
- 6. PC – Relative Addressing Mode Eg:1. beq $s1, $s2, 25 Eg:2. bne $s0, $s1, 20 if($s1==$s2) goto PC+4+100 if($s0!=$s1) goto PC+4+80
- 7. Pseudo Direct Addressing Mode Eg:1. j 2500 Eg:2. jr $ra Eg:3. jal 2500 go to 10000 goto $ra $ra=PC+4 goto 10000
- 8. EXAMPLE Loop: add $t1,$s3,$s3 add $t1,$t1,$t1 add $t1,$t1,$s6 lw $t0,0($t1) bne $t0,$s5,Exit add $s3,$s3,$s4 j loop Exit: 35 9 8 0 0 19 19 9 0 32 5 8 21 2 2 2000 8000 8004 8008 0 9 9 9 0 32 0 9 22 9 0 32 0 19 20 19 0 32 8012 8016 8020 8024 8028 Starting address 8000

Editor's Notes
- Notes to presenter: Description of what you learned in your own words on one side. Include information about the topic Details about the topic will also be helpful here. Tell the story of your learning experience. Just like a story there should always be a beginning, middle and an end. On the other side, you can add a graphic that provides evidence of what you learned. Feel free to use more than one slide to reflect upon your process. It also helps to add some video of your process.
