The article describes a variable high-speed incremental computer that adopts the basic concept underlying a digital differential analyzer (DDA). Its structure closely resembles that of a microprocessor and includes the following features: floating-point arithmetic, a word-length transfer with the elimination of a residue (R) register, multibit multiplication, and a flexible software scheme of interconnections that includes the use of a stack to avoid redundant operations. The proposed structure has been simulated by solving a variety of differential equations with distinctly accurate results.
