An execution architecture for FP

FP is a functional programming language proposed by John Backus to liberate programming from the “von Neumann Style.” We define here an architecture (FP machine model) that is intended to allow easy and efficient implementation of FP on a conventional von Neumann machine. We present a new execution architecture for FP based on Johnston's contour model and on Hoevel and Flynn's notion of DEL/DCA architectures. We call our architecture DELfp, a Directly Executed Language for FP.
