HOTBM: a VHDL Generator for the Higher-Order Table-Based Method

Participants : J. Detrey, F. de Dinechin.

HOTBM is a VHDL generator for fixed-point function evaluation operators using the Higher-Order Table-Based Method [35] . 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.
