Abstract: “This paper describes the implementation of a functional programming language interpreter. The interpreter is written in Forth and runs on any Forth system, including a novel processor called the Scalable Configurable Instrument Processor (SCIP), designed at the Johns Hopkins Applied Physics Laboratory. The combination of this novel processor, Forth, and functional programming provides a layering of simple technologies that yields a unique programming and execution environment. The SCIP processor also has a clear transition path to use in space-borne applications.”
