ABSTRACT:
Integrated circuits for performing calculations such as carry propagate addition where the number of logic stages necessary to perform each calculation is proportional to log.sub.2 times the number of bits on which the calculation is performed. The circuits are divisible into a limited number of cells, thereby minimizing complexity, for ease of design and manufacture. Each cell comprises a device for accepting a bit or bits from an operand or operands and a device for accepting intemediate binary tree values. The cell then combines the input information to produce an arithmetic resultant and intermediate binary tree values for a next succeeding cell.
