A new methodology to study irregular behaviours in logic cells is reported. It is based on two
types of diagrams, namely phase and working diagrams. Sets of four bits are grouped and …

Based on the negabinary number representation, parallel one-step arithmetic operations
(that is, addition and subtraction), logical operations, and matrix-vector multiplication on data …

We present, for the first time to our knowledge, a generalized lookahead logic algorithm for
number conversion from signed-digit to complement representation. By properly encoding …

A new modified signed-digit (MSD) addition algorithm based on binary logic gates is
proposed for parallel computing. It is shown that by encoding each of the input MSD digits …

The given paper considers problems dealing with design of optoelectronic trigger devices
with optic inputs based on devices with λ-volt-ampere characteristic including λ-diodes and λ …

A new design approach for a three-step modified signed-digit (MSD) adder is presented that
can be optically implemented using binary logic gates. The proposed scheme depends on …

In binary digital computers addition is performed employing the carry propagation technique,
which essentially limits the computing speed. For multiplication the speed is further reduced …

This paper presents a new concept for the realization of a high-speed, high-resolution
Analog-to-Digital Converted (ADC). The approach modifies an analog fiber optic link with a …
