A description is given of the VLSI implementation of a third-generation symbolic processor optimized for the Lisp language. The design effort has resulted in a single-chip implementation of a complete CPU which efficiently executes Lisp primitives and offers performances, system integration, and manufacturability advantages over current approaches to Lisp processors. These advantages are outlined.
