- Fix the MC (Monte-Carlo) to the proper algoritm name, ML (maximum
likelyhood) and remove HalfPi since the use of divider allow to
theoretically support any pi / 2^k, k an integer. In reality, a too
low rotation would require more stages than 7 but it is for futur
improvements.
- Make use of `divider` template to provide rotation grain finer than pi
/ 2. Validated (unit-tested) with pi / 4 with the same margins than pi
/ 2 (2% of error with floating scaling, 3% with fixed scaling).
- Fix rom size which now use N_STAGES+1 bits instead of 8 regardless of
N_STAGES. Simplify the cordic method implementation, which
unexpectedly (and fortunately) improved its performance.
- Commit title implies possible Xilinx Vivado HLS 2019.1 support, thus support
for e.g. all USRP Series 3 from Ettus.
- Add a new CORDIC version, Rom based and meta-programmed via CMake
features, to be even compiled with earlier GCC (not quite tested, but
by changing constexpr to const and using gcc 4.6 -sdt=c++0x, it
worked).
- Class name modified, to be more explicit.
