CyclonePC and OS

[Pangamini]

Well good luck with this... i just dont understand why you emulate CPU on E2, why not use CPU instead?

And BP, i was thinking about making some simple OS that would be able to load CPU programs from external sources like chips or CDs, but i never found a solution for one thing - when assembler is translated into opcodes, all variable pointers are translated into exact memory location right? Then if i store program somewhere else or i load 2 programs at once, how can i execute it? Hm am not sure if i explained clearly what i mean...

Because my CPU is not zCPU. It has a different architecture.

I believe zCPU has a register for movable code. It should act as an offset to every read/write operation. Let me lookup the documentation...
I think that's the one, look for it in documentation:

RM value: 42..49  | General register #1..#8 + direct value |example: MOV 123:EAX

Also, a macro for something similar:

OFFSET <delta_offset>;

You have segment registers. Real address = segment register + offset. So if you want to put your code at offset 12345, you set CS (code segment) to 12345, and it will use old memory pointers (it uses "5" that was specified in original program, but real address in memory is 12350).

DS is used when you read/write to variable without specifying register, CS is used when reading opcodes (you can only change it with jmpf/callf opcodes)

Well this looks like another wireos sort of thing but as i see it is e2, well done another e2 os. well the idea of making your own overly complex pcmod with custom everything is a good idea and i must say if you keep it e2 and make wire in e2 or evern better virtul wire.

Except that most other E2 OS is simply a graphical menu system with a few hardcoded options. This one, like WireOS, is pretty much a real one, since it supports writing your own code from inside the OS, and running C programs, etc etc.

well wire os does use a monoliptic( all drivers run in kernal mode )kernal and yes it is a ture os running on a embeaded platform and so therefore could possabliy run on a real computer insted of a wiremod coumputer

Okay, I figured writing the whole thing in assembly would be next to impossible so I need a C compiler first.
Should I ask someone to rebuild ZC or make my own? Or I could also try to retarget small-C compiler. So Black Phoenix, how did you do it?

[Tasuit]

Download the ZC32?..

[Whodunnit]

programming a compiler is no trivial task i think... start with a lexer? xD

ZC was built on a small C compiler i think.

there are more of such registers? what are their names?
