Abstract :
The availability of 4-valued I2L circuits presents a new perspective for digital systems designers. This correspondence explores several aspects of digital system design using 4-valued logic elements. An approach to designing the ith stage of an ALU employing these elements is presented. The realization of rudimentary ALU operations is shown using the T-gate as a universal building block System design based on both Post and Boolean 4-valued logics is discussed.
