The e ciency of delay depends to a large extent on the following four basic operations: delay, wakeup, interrupt, and resume. Traditional implementations of delay in the WAM are slow because three out of the four basic operations need to save or restore the argument registers. In this paper, we present a novel method for implementing delay in a Prolog machine called ATOAM. The main idea is to store delayed calls as frames, called suspension frames, on the control stack rather than as records on… CONTINUE READING
