Question

Please convert the following bit pattern to a MIPS instruction.

0000 0001 0110 0110 0100 1000 0010 0000

1000 1101 1001 1010 0000 0000 0001 1100

Answer 1

Converting bit patterns to a MIPS instruction.

bit pattern 1:

0000 0001 0110 0110 0100 1000 0010 0000

The first 6 digits 000000
The given code is for ADD instruction.

Splitting the opcodes:
000000|01011|00110|01001|00000|100000

Instruction:
ADD rd,rs,rt

opcode	rs	rt	rd	shift amt	function
6 bits	5 bits	5bits	5bits	5bits	6 bits
000000	01011	00110	01001	00000	100000

Registers for codes

01011 --->$t3

00110 --->$a2

01001 --->$t1

Complete Final instruction :

add $t1,$t3,$a2.

bit pattern 2:

1000 1101 1001 1010 0000 0000 0001 1100

The first 6 digits 100011
The given instruction is for LW instruction.

Splitting the opcodes:
100011|01100|11010|0000 0000 0001 1100

Instruction:
LW rt,offset(rs)

opcode	rs	rt	address
6bits	5bits	5bits	16bits
1000011	01100	11010	0000 0000 0001 1100

Registers for codes

01100 --->$t4

11010 --->$k0

Offset address in the code must be hexadecimal

0000 0000 0001 1100 into hexa is

0000-->0

0000-->0

0001-->1

1100-->C

Therfore hexa code:

0x001C

Complete Final instruction :

lw $k0,0x001C($t4)
