Fixed point versus floating point

Abstract

This paper discusses the advantages of using fixed-point arithmetic in a hybrid environment. The particular ex ample used is that of a hybrid simulation system. The paper discusses the performance penalties which are paid in using floating-point arithmetic as opposed to fixed-point arithmetic. The paper points out the amount of digital- computer time used in fixed-point to floating-point con version. It also suggests a new hardware device, a floating point/fixed-point digital-to-analog converter. This paper points out one application in which this device could be useful.
