ABSTRACT:
A central processing unit and a digital data processing system for performing arithmetic processing of numbers that are not presented using traditional 10 radix signed digits 0, 1, 2 . . . 9. The central processing unit and digital data processing system of this invention are configured to process numbers that are from a set of digits {X.sub.1, X.sub.2 . . . X.sub.2n+1 } wherein each of these digits represents a number between -n, . . . -1, 0, 1, . . . n such that n is an integer and n.gtoreq.1. Thus, for any number that comprises more than one digit the most significant digit represents both magnitude and positive
egative state of the number and the remaining least significant digits each have a radix of (2n+1).
