Detailed descriptions, including block diagrams and instruction set summaries, are given for seven stack processors from Harris Semiconductor, Novix, Johns Hopkins University/APL, MISC, WISC Technologies, and Wright State University. Major topics covered also include architectural analysis of stack machines, software issues, application areas, and potential for future development.
