will your assembler know intrinsic types like int, float?
and if it is planned, is function overloading through name mangeling and simple oop planned?

Hi! Thanks for all the interesting videos - really enjoyed watching your series!

Which CPU are you using to model your VM?
Do you have a target instruction set that can be used for reference?

Hi Francis,

I noticed there's no status register. Therefore no carry.
How can we do a more-than 16bits addition ?
How can we do a ROL/ROL ?

Cheers.

Hi I am following your excellent tutorial series on youtube because I wanted to learn about computers

However, I am doing this In rust a whole different language and I tried to port the memory mapper to rust but I couldn't

So I am asking for a better explanation if you can for example you have

const region = {
      device,
      start,
      end,
      remap
    };

I know start and stop are 16-bit memory addresses but I have some trouble with device and how it talks between the CPU and the memory

Kind regards Stan

ive started a dotnet core port of your project:
https://github.com/furesoft/16Bit_VirtualMachine_Port

when will be a part available to implement Labels?

Hi Francis,

I was wondering why you didn't choose to encode the registers into the opcode....
You mentioned at some point you prefer not to do it I believe to have more room for choice later.
I agree.
Nevertheless, we have 16 bits for encoding.... ;)
What about having for some opcodes something like
opcode:8 reg1:4 reg2:4
?
256 possibilities for opcode are plenty, don't you think ?

Cheers.

hi, i am writing my own vm, but in csharp. i like your series but when will the next episode about memory mapped io be available?
