Hello!

I have a task: implement copying integer array using VHDL for stack, GPR 
and accumulator structure. In generally I understand how this three 
structures works. However I do not understand how to program it. Could 
anybody help with this task?

Helping means: you start with something and then we discuss about it.
Its not the same like "can anybody do my homework?"...

There is no "usual way" to implement those three components.
A stack can be only a two level hardware stack like the first PICs had, 
or it could be a register set on which a stack based Computer is 
working.
A GPR can be one memory cell or a special register set in a processor.

So: start with your description of the structure (it is not a 
"program" you are writing, otherwise it would be VHPL instead of VHDL!) 
and when you encounter specific problems, then ask.
