ABSTRACT:
An arithmetic unit, particularly for floating point operations, is provided in which numeric words with n digits, shifted by any desired number of digits, can be taken, in one step with a duration independent of the extent of the shift, from a shift array which is constructed from tri-state elements in a triangular matrix.
