But you were talking about the Forth code modifying the hardware of the 
processor rather than just compiling code.

Yes, I should have used the house power meter as my example (jokingly of 
course).  Actually, you don't often measure current of low power 
processors directly with an amp meter.  Meters usually drop more voltage 
than is appropriate for powering digital electronics.  Rather you can 
insert a very small series resistance and measure the voltage on that 
with a high impedance millivolt meter.

Again, I'm not clear on what you mean here.  The GA144 is actually a 
poor example in my book.  It is not a good chip for most applications, 
so comparing it to other processors is hard.  Often it requires external 
support circuitry and so ends up more expensive, larger and more power 
consuming.  Not much point in analyzing code running on a chip that 
isn't actually part of an application.  Any application should be 
measured in the full context of the solution, not just a small piece of it.

There should be a few applications where the GA144 can do well.  I'm 
just not familiar with them.

If you generate VHDL any compiler can synthesize it.  My point is that 
extending the processor is only useful for some small subset of the code 
you write, usually to improve speed.  In those cases why not just code 
VHDL directly?  I think it would be a *huge* job to write an optimizing 
compiler that would turn Forth code into HDL or harder, directly to the 
hardware.  Even then the Forth code would likely need to be specialized 
to make it easily synthesizable.

There are efforts to do this with C actually.  You can use a subset of C 
to write code that is translated to Verilog (if I remember correctly). 
The idea being that you can code an application and compile some parts 
to hardware and other parts remain as software.  Change the dividing 
line as your requirements for speed change.  It has not taken off.  I 
think the complexities of the task are not so small and even though both 
are written in C, the coding methods are very different between software 
and hardware.
