Abstract:

This volume summarizes a study whose principal objective was the design of a computer architecture to execute a higher order aerospace programming language directly, without the use of a compiler or interpreter. Background is presented on direct execution and its rationale for aerospace programming, which is principally to reduce total system costs. An analysis is given of the language-related tradeoffs involved in implementing a direct execution architecture, and preprocessor tradeoffs are also presented. Highlights of a functional design of an architecture and preprocessor for a subset of Space Programming LanguageMark IV are presented, including the approach of using transduction equations. Recommendations are made for further design refinement based on the results of a hardware evaluation of the design developed in this work against a conventional aerospace computer programmed both in assembly language and in a compiler-implemented higher order language.
