Question

I want to write two programs using the MIPS assembly language of at least 5 lines

Answer 1

Program to print hello world

# "Hello World" in MIPS assembly # From: http://labs.cs.upt.ro/labs/so2/html/resources/nachos-doc/mipsf.html                 # All program code is placed after the  # .text assembler directive     .text   # Declare main as a global function     .globl  main     # The label 'main' represents the starting point main:         # Run the print_string syscall which has code 4         li      $v0,4           # Code for syscall: print_string        la      $a0, msg        # Pointer to string (load the address of msg)   syscall         li      $v0,10          # Code for syscall: exit        syscall         # All memory structures are placed after the    # .data assembler directive     .data   # The .asciiz assembler directive creates       # an ASCII string in memory terminated by       # the null character. Note that strings are     # surrounded by double-quotes msg:      .asciiz "Hello World!\n"

Program for loop

# Simple routine to demo a loop # Compute the sum of N integers: 1 + 2 + 3 + ... + N # From: http://labs.cs.upt.ro/labs/so2/html/resources/nachos-doc/mipsf.html         .text   .globl  main main:      # Print msg1    li      $v0,4           # print_string syscall code = 4         la      $a0, msg1               syscall         # Get N from user and save      li      $v0,5           # read_int syscall code = 5     syscall         move    $t0,$v0         # syscall results returned in $v0       # Initialize registers  li      $t1, 0          # initialize counter (i)        li      $t2, 0          # initialize sum        # Main loop body loop:  addi    $t1, $t1, 1     # i = i + 1     add     $t2, $t2, $t1   # sum = sum + i         beq     $t0, $t1, exit  # if i = N, continue    j       loop    # Exit routine - print msg2 exit:       li      $v0, 4          # print_string syscall code = 4         la      $a0, msg2       syscall         # Print sum     li      $v0,1           # print_string syscall code = 4         move    $a0, $t2        syscall         # Print newline         li      $v0,4           # print_string syscall code = 4         la      $a0, lf         syscall         li      $v0,10          # exit  syscall         # Start .data segment (data!)   .data msg1:     .asciiz "Number of integers (N)? " msg2:        .asciiz "Sum = " lf: .asciiz    "\n"
