MIPS Tutorial 3 Hello Assembly! Video Lecture | MIPS Assembly Programming Simplified - Electronics and Communication Engineering (ECE)

what's up guys my name is Emil and well
welcome back you made it you made it to
the third tutorial and well now it's
time to start coding our first program
and before that well I want to remind
you that you have to go to smartphone
your comm because we have a lot of
interesting information there and
without any further ado let's begin our
first program in order to make a program
we're going to go to file and then new
and now we have a new file but before
that I always like to save it so click
on this button right here to save and
then I'm gonna save it to my desktop so
give it a name I'm gonna name it hello
assembly that ASM always it needs to
have a ASM because ASM is for assembly
so that's the file extension so save it
to your desktop and now we can start
coding now we can start programming so
first of all every MIPS program has two
sections the data section and the text
section so always type that data and
then that text that data as the name
implies has all the data of your program
like if we were writing in C++ or Java
it would be like all the variables and
the text section it has all the all the
instructions that you need that your
program needs so that's what you need to
do define these two sections so what I
want to do in this program is that I
want to write a program that's going to
say hello world to the spring so in
order to do that I'm gonna have to I'm
gonna declare a message hello our hello
world and I'm going to call it my
message this is a name
this is the name of my message and I'm
going to place it in random access
memory but before that I have to tell it
what data type my message is so like
data
five here you have word ASCII so I want
ask easy and this is just text and text
has to go in quotation marks between
quotation marks so I'm going to say
hello world and for a newline I do
backslash n so this means like a print
hello world I mean not printed but this
is just hello world and then you learn
so now I go to my dad text and this is
where I put my instructions
so I say load immediate dollar sign V 0
comma 4 don't worry if you don't
understand what I'm doing I'm gonna tell
you what this means and then this is
just like this is just like a signal
you're telling the system okay get ready
because now you have to print something
so prepare for that so you telling the
system what the system has to do and
then what do you want to print well I
want to I'm going to say the value of my
message I want to print out the value of
my message what's the value hello world
so I have to put this value in a
register because that's the only way I
can print it out and by convention we
use the TA register but in this case we
have to use the register anyways so lo
the address so lo the address in Dallas
area is 0 of my message so it means um
hi
system please print our message print
out text and then the system you need to
tell what text so lo the address of this
variable this is in random access memory
loaded into the register or into the
processor into this register right here
and it's all the time you have to put it
in a zero because that's the way it
works and now that you have all these
things all the information you say ok do
it do it now so this is going to do it
and then we go to run assemble it was
successful right here you see that the
program completed successfully and now
we can run it I mean just go to this bar
right here click it voila voila here it
is hello world congratulations now you
are programmers
I mean assembly programmers you make
your first programming assembly hello
world well let me go over the program
again we have two sections the data in
that text that data contains to the data
in this case all the values that are
storing in random access memory and that
text contains all the instructions so
these three instructions what they do is
that they print out a value to the
screen but not any value only ASCII
values only text so all the time when
you want to print out text you have to
say put a value for in register V 0 and
it's say when you put a value for in
this register it means that you that the
system will know the system will know
that you want to print out a value to
the screen and then what value ok put my
message from random access memory from
random access memory put it in this
register is 0 so now the system knows
now the system know that you want to
print out something and it knows that
what you want to pronounce that message
and now you just say ok execute it or do
it in the Sisqo so you can see right
here hello world congratulations you
made it don't forget to subscribe thank
you next time I know I will show you
something very interesting again and
thank you very much
take care
