Re: [oc] FPU?

[Long Truong <lxtruong@ieee.org>]

Sure.  I'm currently involved in a school project that is implementing the
ARM7 core.  We're using a ARM10 FPU, but since I dobut that we'll wanting
to be using anything related to ARM, I'll take some time this week and start
researching FPU concepts, since I have little to no knowledge of how it
works. 

So, anyone who wants to join the soon-to-be-created FPU project, mail me.
Also, if there are any people with insights into floating point with any
wisdom to share, please don't hesitate to tell me.

Oh, and btw, Verilog is my HDL of choice.  Since I just heard about
Opencores yesterday (eetimes article), I don't know if you guys care about
the language implementation?
