!!!OLD!!! ZCPU Documentation

[Black Phoenix]

Those scripts are testing, they may not work. Speed test, as far as I know, outputs some integer on port5 all time. Try attaching screen.
Don't take those scripts as something to learn from, better use tutorials posted here

I was looking through the documentation and I could not find a power command. For example x^2. Does this function not exist for the cpu yet?

[Black Phoenix]

Not as working opcode.

[Razara]

a quick fix i found to get a square of something is just

mul eax,eax;

i'm sure that's trivial, it might just help some people out. To get other power functions one could

mov port0,eax; //attach port0 to a power gate setup with a value determining to what power the function is
mov eax,port0;//attach the output of the power gate to port0

[Black Phoenix]

Last code is too slow. It will be skipped on high frequencies

[Razara]

if i understand the halt command correctly would this remedy it? it should theoretically halt the program until the power function did its calculations.

mov port0,eax; //attach port0 to a power gate setup with a value determining to what power the function is
halt 0;
mov eax,port0;//attach the output of the power gate to port0

[Black Phoenix]

Yeah, that's right. HALT will pause until some new value comes on porn 0.
That should work even on high frequencies

**edited** nvm found problem

[XeonXT]

Yeah, that's right. HALT will pause until some new value comes on porn 0.[/b]

...

Anywho, when's this GPU coming out?

[Seraphis]

mainloop:
mov eax,port0;
cmp eax,1;
je z;
cmp eax,1;
jne mainloop;
z: // Start Letter Z
mov ecx,0;
mov ebx,1;
mov port1,ebx;
jmp lineone;
lineone: // Start Line One
mov port2,1; //x
mov port3,0; //y
cmp ecx,100;
jg linetwo;
inc ecx;
cmp ecx,100;
jng lineone;
linetwo:

Having problems with this, still kindof new at it... Could anyone tell me whats wrong with it?

Basicaly, when port 0 has the value of 1, it's supposed to jump to label z, Which is then supposed to keep port 1 at value 1, but go on like a for loop timer until ecx is greater than 100 (timer), but while it is less than 100 it will keep port 2 at 1, and port3 at 0 and turn both to 0 when it's greater. Apon being greater, it will jump to linetwo and start a similar timer loop but with different port2 and 3 values.

I hope this wasn't too confusing... And I realize my code is probably way off.
