computer organization

1. Study the code to understand the array memory arrangement and loop operation using beq and j assembly instructions.

2. Now, modify the program to declare another integer type of array called array2:

array2: .space 32 #size of the array (8) x word size (4) = 32 bytes

3. Modify the code to copy the contents of the array to array2.
4. Modify the code to display the contents of array2
5. Assemble and execute the code and also observe the output.
6. Modify the code to add all elements in array and display the result.
7. Assemble and execute the code and also observe the output.
8. Submit the Lab05.asm file on Canvas.

the code is below:

.data array: .word 10, 11, 12, 13, 14, 15, 16, 17 # int array[8] = {10, 11, 12, 13, 14, 15, 16, 17}; size: .word 8 # size of the array = 8 comma: .asciiz ", " # Comma seperator for display ################################################################################################### # We will use a loop to access all the array elements one at a time and display that to the screen. # ARRAY_SIZE = 8; # int i = 0; # while( # int i = 0; ; i++){ # printf("%d",array[i]); # } ################################################################################################### .text la $t0, array #load the starting address of the array to the register $t0 #set the loop control variables lw $t1, size #load the size of the array to the register $t1 li $t2, 0 #set $t2 to 0.
