  • addi $s0, $zero, -15

          Format:

                 Opcode(6-bit)        rs(5-bit)       rt(5-bit)      immediate(16-bit)

                    addi                    $zero       $s0 -15

                 001000                  00000          10000            1111111111110001

Hex: 0x2010fff1

---------------------------------------------------------------------------------------------------------------------

  • slt $t0, $s0, $s1

        Format:

           opcode(6-bit)       rs(5-bit)        rt(5-bit)      rd(5-bit)      shamt(5-bit)       func(6-bit)

           slt                        $s0               $s1             $t0   

            000000               10000           10001         01000      00000                101010

Hex: 0x02114020

-----------------------------------------------------------------------------------------------------------------------------------------

  • beq $t0, $zero, LEEQ

                 Here i assume LEEQ label after 'j' instruction

               Format:

                 Opcode(6-bit)        rs(5-bit)       rt(5-bit)      offset(16-bit)

                    beq                     $t0    $zero    1(After 1 instruction)

                 000100                  01000       00000           0000000000000001

Hex: 0x11000001

--------------------------------------------------------------------------------------------------------------------

  • j GRT

          Here i assume GRT label is the start label

        Format:

                 opcode(6-bit)             Target(26-bit)

                000010                     ox00003000(I assume )

              000010                  00000000000011000000000000>>2(shift 2)

           000010                    00000000000000110000000000

Hex: 0x08000c00
