MATHEMATICAL LOGICAL OPERATING METHOD AND MATHEMATICAL LOGIC COMPUTING ELEMENT

摘要

PURPOSE: To provide the high-speed mathematical logical operating method and mathematical logic computing element reducing the amount of a hardware. ;CONSTITUTION: Three selective inputs P₀-P₂, carry inputs Ci-₁ and two data inputs Xi and Yi are defined as inputs, and as logical elements to output a data output Si and a carry output Ci by executing logical arithmetic, inverters I11-I14, AND gates A11-A17 and OR gates O11 and O12 are provided. Further, a full adder 11 is provided as well.;COPYRIGHT: (C)1993,JPO&Japio
