Regarding some information,
I updated the FPU page in opencores site you can check for some links
I want to add a link for the x86 architecture http://www.x86.org we can find
some information about the coprocssor.

Where can I find the OR1K interface for the FPU. I think we can should be able
to build this FPU to be able to run as a stand alone core and so to be plugged
to any other processor. what do you think?

check the fpu page
