Data processor with read-only-memory processor and partial solution push-down stack

摘要: A data processor such as a programmable logic controller utilizes read-only-memory boolean for generating solutions to complex equations. The includes plurality of address inputs selectively addressing memory locations thereof in accordance with applied and multi-bit instructions. contents the addressed location represents solution or partial equation. memory, form push-down stack reversible serial storage means, is coupled output receiving storing single-bit solutions, an input transferring stored therein means further processing. are predetermined order transferred from processing reverse said order.
