Arithmetic processor for multiplication, division, addition and subtraction - introduces extra control stage to enhance multiplier and subtractor circuit

摘要

The electronic digital circuit provides a full arithmetic processing capability fo multiplication, division, addition and subtraction. The processes are provided by adder stages together with shift registers with the mode operator provided by a control circuit-generating a number of gating or enabling signals. The control circuit has counter logic (23) together with pulse generating logic. One section of the controller provides the additional operations for addition and subtraction of flowing point numbers as well as the multiplication and addition operations. USE/ADVANTAGE - Provides multiplication, division, addition and subtraction.
