Digital multiplication and division circuit - controls decimal point and registers by simple logic unit

摘要

An electronic digital circuit is used for the multiplication and division of numbers decimally coded in 5211 weighted code. A specific circuit is provided for the control of the decimal point position and the shift registers used for value storage. The circuitry has shift registers (3,4) to store the values entered and generated during the arithmetic processing. Control of the units is provided by a circuit that uses four flip-flops and a limited number of AND and OR-gates. ADVANTAGE - Simplified control logic.
