How To Print Out Value At Register In Mips

If you take but started Mips Assembly, after learning syntax first basic program you learn is either printer a "Hello world" or reading and print integer or character. In this department, we will learn how to print an integer from a annals and how to read an integer from the keyboard. So let's get started!

MIPS Print Integer from Register

Commencement, consider the post-obit MIPS program to print an integer from a register:

[lawmaking]

.data
.code

li $to,four

li $v0,i
move $a0,$t0
syscall

li $v0,10
syscall

[/code]

Explanation

In the above program, nosotros take taken a register $t0 to shop an integer. Then we used a syscall service to print that integer. To print that integer we have to move that integer to a register called $a0. The $a0 register is used to store a string, graphic symbol or integer output.

MIPS Read Integer from Keyboard/User

To read an integer in MIPS we have to use a syscall service for reading an integer. Consider the example to read an integer.

[lawmaking]

.information

msg1: .asciiz "Enter a number: "

.lawmaking

li $v0,4
la $a0,msg1
syscall

li $v0,5
syscall

li $v0,10
syscall

[/lawmaking]

Explanation

In the above program, we take used a syscall service "5" for reading an integer. Nosotros take used a label "msg1" to inquire a user to enter a number. In case you don't want to print the message and just want to read the number just remove the msg1 lin in .data department and in .lawmaking department remove the corresponding lawmaking for printing the msg.
