Preliminary Design and Implementation of an Ada Pseudo-Machine

摘要

This project involved defining an Ada pseudo-machine and developing an Ada to pseudo-code test translator. The translator's front end incorporates a table-driven parser that can parse the entire proposed-standard Ada language. The translator's semantic routines allow integer data objects, several control structures, procedures, functions, packages and tasks. These routines generate pseudo-code that is executed by an interpreter program included in the translator. The interpreter constitutes a complete description of the pseudo-machine whose architecture consists of multiple, stack-oriented processors that access a common memory. Interesting features of the project include the hash-coded symbol table that supports Ada's visibility rules and the pseudo-machine architecture that supports Ada's tasking. (Author)
