Abstract

Disclosed herein is a computing system with the capability to execute instructions in different positional notation values. The definition of a positional notation value is given by the general formula that represent a base 10 numeral in any positional notation in the following manner: . . . d3r3+d2r2+d1r1+d0r0, where d is a coefficient, r is the base of the positional number system (i.e. r=2 for binary, or r=3 for ternary), and the exponent is the position of the digit. The computing may provide a configuration which hybridizes the instructions of multiple positional notation values in variable ratios. The computing system may dynamically switch between the multiple hybridized instructions sets. Embodiments may be applied to provide security benefits.
