A question for computer architects who dabble in AI. What are the characteristics of a machine architecture which has good prolog and/or lisp performance? Are RISC machines likely to be as good as machines with special hardware like the Symbolics machines? Why do the primitive data types I have seen use several bits of each word as a tag? Wouldn't a separate word (or byte on byte machines) give much better performance on currently available hardware at the cost of memory space? Is this cost too high?
