"VHDL Library of Arithmetic Units"

R. Zimmermann

Abstract
--------

A comprehensive library of arithmetic units written in synthesizable VHDL code
has been developed. The library contains components for a variety of arithmetic
operations and for different speed requirements. The library components are
implemented as circuit generators in parameterized structural VHDL code. Their
modular and well-documented source code allows for simple usage and easy
customization. Highly efficient circuit architectures are used, which are
optimized for synthesis and cell-based design. The VHDL library is platform
independent, and it provides circuits with comparable performance, but higher
flexibility and a larger diversity of arithmetic operations compared to
commercial data path libraries.
