ARITHMETIC CALCULATOR BASED ON NEURAL LOGIC ELEMENTS
Annotation
An arithmetic calculator that performs addition and subtraction operations with numbers in a fixed-point format in direct code and is built on elements of neural logic, is presented. Arithmetic operations of summation or subtraction are performed by analyzing the operation code and signed digits of numbers. If the sum of the sign bits of binary numbers and the operation code is equal to zero, then the summation operation is performed, otherwise - subtraction. When summing, the transfer from low to high digits is determined; when subtracting, a loan from high to low digits is calculated. The proposed device has increased computing speed, and the use of neural-like elements allows reducing hardware complexity.
