HOTBM: a VHDL Generator for the Higher-Order Table-Based Method
HOTBM is a VHDL generator for fixed-point function evaluation operators using the Higher-Order Table-Based Method  . The key features of this method are:
- piecewise polynomial approximation,
- parallel computation of all the terms,
- ad-hoc powering units,
- optimized look-up tables,
- small multipliers,
- and guaranteed faithful rounding.
