Question

Write a MIPS program that prints(displays) "Hello World" using MMIO (NOT syscall!)

Here is a screenshot of a MIPS program that prints user input to the screen. And I need something that displays "Hello World" without taking any input. Please help! Thanks.

The output should be something like this but without the input

.data 7 strl:.asciiz "\nStart entering characters in the MMIO Simulator" .text 10 .globl echo 12 13 14 15 16 17 echo: al Read # single print statement la $a0, strl syscall # reading and writing using MM10 # in an infinite loop add $a0, $V0, $zero jal Write j echo 18 19 20 21 22 Read: ui $t0, 0xffff 23 Loopl: lw $t1, 0($t0) 24 25 26 27 28 29 Write: lui $t0, 0xffff 30 Loop2: lw $t1, 8($t0) 31 32 #ffff0000 #contro andi $tl, $t1,0x0001 beq $t1,$zero, Loop1 lw $v0, 4($t0) jr $ra #data #ffff0000 #control andi $t1, $t1,0x0001 beq $t1, $zero, Loop2 Sw $a0, 12($t0) jr $ra #data 34 35 Keyboard and Display MMIO Simulator DISPLAY: Store Oxffff000c, cursor 15, area 113 x 12 to Transmitter Data Hello World!

Hello, Please try the following code.

.globl main
.data
prompt:
    .asciiz  "Hello world!"
.text
main:
    addi $v0, $zero, 4
    lui $a0, 0x1001       # $a0 = 0x10010000
    syscall
rtn:
    jr $ra
