Digital electronic circuit for addition subtraction multiplication and division - has tetrade circuit for addition and subtraction, and adder operated in switched mode together with shift registers operated by pulse generator

摘要

The circuit is based around a 4 bit arithmetic circuit that is operated together with gating logic that allows switching between addition and subtraction modes. The unit operates together with a shift register unit that interacts with a second unit to perform the operations. The pulses required for the shift register transfers are provided by a pulse generating circuit. USE - Provides all 4 basic arithmetic operations.
