ON PORTABLE MACROCELL FPU GENERATORS FOR DIVISION AND SQUARE-ROOT OPERATORS COMPLYING TO THE FULL IEEE-754 STANDARD

In this paper, rye investigate the design of macrocell generators of d ivision and square root floating-point operators, The number represent ation used in our operators is the IEEE-754-1985 standard for binary f loating-point numbers, The design and implementation of the generators rely on a powerful multiview macroblock generator tool called GenOpti m. This computer-aided design (CAD) tool is able to output a set of di fferent descriptions for several VLSI technologies as well as field pr ogrammable gate arrays (FPGA's). The division and square root operator s described in this paper use the signed-binary-digit representation, We start first by describing the operators for the significand, then w e investigate the IEEE floating-point operators, All along this paper, and wherever appropriate, we present the implementation results using the GenOptim environment.
