Abstract

The results of investigations of scaling operations in the opticallyimplemented adaptive processor are presented. It is shown that blind scaling can be employed to reduce the necessary numerical range of the system but that protection again pathological situations diminishes its allowable extent. Extended-accuracy studies have shown that much greater reduction of range could result. The applicability of algebraic integers to achievement of extended accuracy in RNS computations is investigated and promising results are reported.
