Several recent posts have referred to a document called CORE ISA. This is a public-domain definition of a computer at the level of a macro-assembler. It gives, therefore, address modes, instruction definitions, logical register names; it does not give instruction formats, bit encodings, &c, and allows the implementor considerable freedom, provided she can also build a translator from the CORE ISA symbolic assembler to the true code of the machine built. If anyone is interested in this document, it is currently maintained and distributed by Software Engineering Institute Carnegie Mellon University Pittsburgh Pa 15231 Please address any correspondence to me Robert Firth firth@sei.cmu.edu
