A Comparison of Architectures for Various Decision Diagram Machines
Hiroki Nakahara, Tsutomu Sasao, Munehiro Matsuura · 2010
This paper compares 6 decision diagram machines (DDMs) with respect to area-time complexity, throughput, and compatibility to the existing memory. First, 6 types of decision diagrams (DDs): BDD, MDD, QRBDD, QRMDD, heterogeneous MDD (HMDD), and QRHMDD are introduced. Second, corresponding DDMs are developed. Third, memory sizes and average path length (APL) for these DDs are compared. As for area-time complexity, the QDDM is the best; as for throughput, the QRQDDM is the best; and as for compatibility to the existing memory, the HMDDM is the best.
