Parallel modified signed-digit algorithms for division, square root, logarithmic, and exponential functions

Parallel one-step addition (subtraction), multiplication, and division is proposed to perform the computation of complex functions such as the square root, logarithm, exponential, and other related operations. An optoelectronic correlator based architecture is suggested for implementing the proposed modified singed-digit (MSD) number system representations based. We utilized the symbolic substitution technique to reduce the number of the computation rules involved.
