ABSTRACT
Dynamic range overflow is a serious problem in residue arithmetic systems. Contemporary overflow management schemes rely on inefficient scaling operations. In this correspondence a residue scaler is architectured which inhibits dynamic range overflow. The system uses the popular three moduli set {2n-1, 2n, 2n + 1}. Using a 4K memory model, practical 12-and 18-bit autoscalers are configured. An error model for the derived residue arithmetic unit is also derived and experimentally verified.
