Edit: regarding the SELFs thing, maybe the S should stand for sh*t since the S in Sony stands for sh*t also I'll go and wash my mouth for that :P

Yes I believe it is in fact PPC64. Here is a test that a developer gave me lol, for educational purposes . The goal is to convert it to C language.
Please if you finish this test DON'T post it anywhere I am still learning myself and haven't finished the test yet .

cellFsWrite:
.set var_10, -0x10
.set arg_10,  0x10
cmpwi        cr7, %r6, 0
mflr        %r0
extsw        %r3, %r3
std        %r0, arg_10(%sp)
beq        cr7, loc_10BE0EF0
rldicl        %r4, %r4, 0,32
rldicl        %r6, %r6, 0,32
li        %r11, 0x323
sc
ld        %r0, arg_10(%sp)
extsw        %r3, %r3
mtlr        %r0
blr
.align 4
loc_10BE0EF0:
addi        %r6, %sp, var_10
rldicl        %r4, %r4, 0,32
rldicl        %r6, %r6, 0,32
li        %r11, 0x323
sc
ld        %r0, arg_10(%sp)
extsw        %r3, %r3
mtlr        %r0
blr
# End of function cellFsWrite

it has been 9 hours since I was given this test and I have not yet finished it, How do these devs do it .

Well... maybe they understand assembly language, that helps :D

Ok... since I'm not able to understand C nor assembly this is simply too much :D
Will give it a try when I put my nose in assembly languages

I too know neither of the two languages but I am learning as I go and so far I have to be honest its a slow process lol.

The way I plan on doing it is commenting what each line does, then after everything is commented I begin the conversion to C as I will now know what I want the C program to do.

Easy in thought but hard in practice..for me at least lol.

If you realy want to learn this stuff and you know that you will still feel the same after 6months, then you should start elsewhere. Even if you solve this "test" you wont get much out of it since you still wont know what you are doing :D

Start with google . Write "Introduction to Computer Engineering".
This one looks OK, start with part1 .

Introduction to Computer Engineering - Part 13 Basic Logic Gates - YouTube

Even if you dont understand everything atleast you get to see some basic stuff, so you can later put things in perspective.

Then go to "simple introduction to assembly". If you can understand assembly language, which is not hard, but a bit "strange" sometimes, then you shouldnt have that much of a problem with C also.
But its a process and it takes time. It works better if you do it in small steps. And you atleast partly understand what are you doing .. GL

Thx for the hints I'm thankful for every bone you throw at me :D
