Architecture and VLSI module generator for expressing digital signals in decibels

View publication

Abstract

An architecture and automatic parametric VLSI design for expressing digital signals in decibels is presented. Both the piece-wise linear approximation and a look-up table ROM was used to compute the logarithm involved. The round-off error analysis is also given and the optimal wordlength of the various sections of the hardware for all input/output requirements is described. A module generator implementing the simplified architecture is presented, it is independent of technology and design rules, accepts any standard cell library, has a wide range of parameters, is easy to use and can be readily interfaced to other CAD tools. © 1991 Taylor & Francis, Ltd.
