This is the latest (and greatest!) in a long series of fully-unrolled
CORDIC processors written by Larry Doolittle, with occasional help
from Ming Choy and Gang Huang. It is written in portable Verilog,
synthesizable for pretty much any FPGA; part of that Verilog is in turn
composed by an Octave/Matlab program.
