[f-cpu] the wrong way (of floating point and so on)

Hello,

I am back from my vacation and I was slayed from your discussions... :)

I think we should forget to trace the way to include floating point now.
Why?
IMHO there are too many tasks to do, which are more important than
thinking about floating point units. First, we should have a working
"simple" F-CPU, not more nor less.
Second, a FPU was declared as an optionally unit,
Floating-point-operations are rare and should be emulated in an
intelligent way (software) to use the full power of F-CPU's
SIMD-capabilities
Last, If we are better in designing units and we have a real (!) F-CPU we
can easily extend the core with an existing FPU, I think.

In my mind I do not realisize how you will design the scoreboard and the
shifting unit in a possible way or I misunderstood anything.

In my opinion we need in near future a working CPU to get and hold a good
developer-basis, and to make tests in reality not in emulations only.

Because we can compose a set of FPGAs (Altera and Co.) to load and emulate
the CPU, we should go in this direction, to make FC0 to that what it is,
"a proof of concept".

I am in right?

Bye Andreas
