Comparing production system architectures
Mark Lease, Mac Lively · ACM SIGARCH Computer Architecture News · 1988
Expert systems have become very popular in recent years. But the forward-chaining production systems (PS) driving the expert systems have severe limitations when run on general-purpose computers. The Match phase of the Match-Act-Select cycle production systems execute is computationally expensive and creates a limitation in the performance the PS's can deliver. This paper examines the architecture of three computers (DADO2, NON-VON, and Production System Machine) designed to speed up the Match process by pattern matching many facts and rules in parallel. The speeds of the designs are compared and the systems are analyzed to determine how suitable they are for use in the commercial environment.
