Abstract: The processor of the present invention executes procedures, which comprise S-language instructions and names. S-languages are of higher order than typical machine languages and can be tailored to user high-order languages. Each procedure includes a dialect code which the processor interprets, enabling it to execute any of a plurality of dialects of S-languages. The processor includes means for resolving names into operand logical addresses. The processor possosses multiple levels of microcode control means, each with its own set of stacks.

Abstract: A data processing system having a flexible internal structure, protected from and effectively invisible to users, with multilevel control and stack mechanisms and capability of performing multiple, concurrent operations, and providing a flexible, simplified interface to users. The system is internally comprised of a plurality of separate, independent processors, each having a separate microinstruction control and at least one separate, independent port to a central communications and memory node. The communications and memory node is an independent processor having separate, independent microinstruction control and comprised of a plurality of independently operating, microinstruction controlled processors capable of performing multiple, concurrent memory and communications operations. Addressing mechanisms allow permanent, unique indentification of information as objects and an extremely large address space accessible and common to all such systems.
