sort in assembly pcspim
To sort in assembly using PCSpim, you can use various sorting algorithms such as bubble sort, insertion sort, or selection sort. Here's an example of how to implement bubble sort in assembly using PCSpim:
.data
array: .word 5, 2, 8, 1, 9, 3, 7, 4, 6 # An example array to be sorted
size: .word 9 # The size of the array
.text
.globl main
main:
la $t0, array # Load the base address of the array into $t0
lw $t1, size # Load the size of the array into $t1
li $t2, 1 # Set a flag to indicate if any swaps were made
li $t3, 0 # Initialize the outer loop counter
outer_loop:
addi $t3, $t3, 1 # Increment the outer loop counter
li $t2, 0 # Reset the flag for this iteration
li $t4, 0 # Initialize the inner loop counter
inner_loop:
addi $t4, $t4, 1 # Increment the inner loop counter
lw $t5, 0($t0) # Load the current element
lw $t6, 4($t0) # Load the next element
ble $t5, $t6, no_swap # If the current element is smaller or equal, no swap is needed
sw $t6, 0($t0) # Swap the elements
sw $t5, 4($t0)
li $t2, 1 # Set the flag to indicate a swap was made
no_swap:
addi $t0, $t0, 4 # Move to the next pair of elements
blt $t4, $t1, inner_loop # Continue the inner loop if not all elements have been compared
beqz $t2, outer_loop # If no swaps were made in the inner loop, the array is sorted
j outer_loop # Otherwise, continue the outer loop
li $v0, 10 # Exit the program
syscall
Please note that this is just an example of bubble sort in assembly using PCSpim. You can modify it or use a different sorting algorithm based on your specific requirements.
