| Sumario: | In this paper a slightly modification is proposed to the original Wong and Gotos ATA method for the computation of elementary functions in IEEE 754 single precision. The identification of a trade-off leads to the proposition of a different chunk of the mantissa that in turn brings a reduction in the length of the tables. Results are reported for usual elementary functions based on exhaustive simulations. A mixed framework including VHDL and Matlab R is used for those simulations. |
