# (Presentation by Silviu-Ioan Filip) A hardware friendly rational function approximation evaluator

On February 19, 2019, 11:00, Dr. Silviu-Ioan Filip will deliver the following talk at the Institute Seminar:

##### Abstract:

In this talk we present an automatic method for the evaluation of functions via polynomial or rational approximations and its hardware implementation, on FPGAs.
These approximations are evaluated using Ercegovac’s iterative E-method adapted for FPGA implementation. The polynomial and rational function coefficients are optimized so that they satisfy the constraints of the E-method.
We present several examples of practical interest; in each case a resource-efficient approximation is proposed and comparisons are made with alternative approaches.
