On the Design of 4-Valued Digital Systems
September 1981 (vol. 30 no. 9)
pp. 666-671
W.C. Kabat, Department of Computer Science, Illinois Institute of Technology
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.
Index Terms:
T-gate, Boolean algebra, digital system design, 4-valued ALU, multivalued logic, Post algebra
