No clue and no interest in cracking the Altera license.

However, we're already implemented a DDC and DUC in the FPGA.  It's
coded in verilog and it's free software.  Before you reinvent the
wheel, you may want to spend a bit of time looking at the existing
code.  The DUC may have suffered some bit-rot.  It's been a while
since we used it.  We do use the DDC in our current build.

If you haven't already downloaded the code, start here:
