-# This is just crafted for testing some ideas, and verifying that we can make
-# it run fast.  It runs at 2.55 cycles/limb on the 630, which is very good.
-# We should play a little with the schedule.  No time has been spent on that.

-# To finish this, the loop warm up and cool down code needs to be written,
-# and the result need to be tested.  Also, the proper calling sequence should
-# be used.
