The FELIN arithmetic coprocessor chip

Abstract

ISBN: 0818607742International audienceA description is given of a general VLSI architecture for the computation of arithmetic expressions including floating-point transcendental functions. This architecture is divided in three parts: a communication machine, the control part of a computation machine, and the operative part of this computation machine. In order to compute the most usual transcendental functions, the authors introduce some general algorithms including, as a particular case, the CORDIC scheme. The major architecture goals were regularity, parameterization, and automatic design. The final chip is designed in a two-ALU CMOS technology, and its name is FELIN (fonctions elementaires integrees)
