It works well - and it is surprisingly fast too...
And its easy if the opcodes are all say one byte,
else you need an opcode length field too, and fancier
parsing.

Not the ones in PCs. The OP didn't specify the CPU that's being used,
however.

I think that PC referred to the CPU's Program Counter.
Argh, thanks. :)
The x86 CPUs if typical Windows PCs aren't RISC but Intel also
manufacture X-Scale (ARM core) processors which are.
Okay, sorry for lack of precision. I was referring to x86.

Well it was meant for a small micro-controller, the PIC-14-series,
e.g. PIC16F877.

If I'm not mistaken, I read somewhere that you can use
function-names/references in lists and/or dictionaries, but now I can't
find it anymore.
The idea is to build a simulator for some kind of micro controller (just
as a general practise, I expect it too be very slow ;-).

Yes. Functions are (so called) first class objects. You can refer to one
by name, and pass that reference around in variables and other data
structures.
That said, your code above won't work as written because function1 is
not in existence when you refer to it.
Yes, I just found that

Python's functions are objects too - instances of the (builtin) class
'function'. So yes, you can use them like any other object (store them
in containers,
