Question

Please use MIPS Assembly language program code to fill in the spaces in the table below.First one has been filed as example

Please fill in the spaces in the table as my example shows: Please use decimal values for the OpCode row, and Hex digits for the Instruction rows Use your Green Card to lookup the required values. Location Program Counter Counter # $t4 = $56 + $s1 12 Opcode Rs 0 32 22 17 Rd 12 Rt Immediate field 000000 10110 10001 01100 00000 100000 32 02D1 6020 36 Additionally, use the Left margin to keep track of the Location Counter, and the right margin to note the value that would be in the Program Counter The initial value of the Location Counter should be zero. The first instruction below is worked.

Explanation / Answer

LW    $t1, 0, ($a0)
Syntax: LW base, targetRegister   offset
Here base is: $a0   (00100)
targetRegister is: $t1   (01001)
And obviously offset is 0   (0000000000000000)
LW instruction code is: 100011
And the binary equivalent is:
100011   00100   01001   0000000000000000
And its hexadecimal equivalent is:
1000   1100   1000   1001   0000   0000   0000   0000
8       C       8       9       0       0       0       0
So, the hex code is: 8C89   0000

ADDI $v0, $v0, 1
Syntax: ADDI target, source, immediate
source and target are both: 00010
And immediate is: 0000000000000001
ADDI instruction is: 001000
And the binary equivalent is:
001000   00010   00010   0000000000000001
And its hexadecimal equivalent is:
0010   0000   0100   0010   0000   0000   0000   0001
2       0       4       2       0       0       0       1
So, the hex code is: 2042   0001

SW $t1, 0, ($a1)
Syntax: SW   target, offset, base
target is: 01001
offset is: 0000000000000000
base is: 00101
SW: 101011
And the binary equivalent is:
101011   00101   01001   0000000000000000
And its hexadecimal equivalent is:
1010   1100   1010   1001   0000   0000   0000   0000
A       C       A       9       0       0       0       0
So, the hex code is: ACA9 0000

ADDI $a0, $a0, 4
Syntax is explained earlier:
source and target values: 00100
And the immediate equivalent is: 0000000000000100
So, the binary equivalent is:
001000   00100   00100   0000000000000100
And the binary equivalent is:
0010   0000   1000   0100   0000   0000   0000   0100
2       0       8       4       0       0       0       4
So, the hex code is: 2084   0004
