We show the advantage of Quarternary Decision Diagrams (QDDs) in representing and evaluating logic functions. That is, we show how QDDs are used to implement QDD machines, which yield high-speed implementations. We compare QDD machines with binary decision diagram (BDD) machines, and show a speed improvement of 1.28-2.02 times when QDDs are chosen. We consider 1-and 2-address BDD machines, and 3- and 4-address QDD machines, and we show a method to minimize the number of instructions.

Trietsch, Dan (Monterey, California. Naval Postgraduate School, 1989-09); NPS-54-89-011Using transfer lots, we can overlap the processing of a batch on several consecutive machines, and thus reduce the makespan considerably. This in turn promotes work-in-process reduction. In this paper we investigate the ...
Shaeffer, Blanca A. (Monterey, California. Naval Postgraduate School, 2000-03-01);Nowadays, it is common to see the use of a network of machines to distribute the workload and to share information between machines. In these distributed systems, the scheduling of resources to applications may be accomplished ...
