Abstract: This paper describes some of the work done at Calgary on the design of an SECD chip and its verification using the Cambridge HOL proof assistant. The chip is a physical realization of Henderson's variant of Landin's abstract architecture to execute the lambda calculus. The machine uses closures and includes explicit machine instructions to assist recursion. The complete proof, which goes from an abstract specification down to the transistor level, is far too involved to be covered in a single paper. In this paper, we discuss the SECD architecture and design and trace through a portion of the proof of correctness of one sequence of the microcode.
