International Classification:

G06F 1300

US Classification:

364200

Abstract:

A data processing system having a flexible internal structure, protected from and effecitvely 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 identification of information and an extremely large address space accessible and common to all such systems. Addresses are independent of system physical configuration.

International Classification:

G06F 934
G06F 946
G06F 1300

US Classification:

364200

Abstract:

A digital data processing system has a memory organized into objects containing at least operands and instructions. Each object is identified by a unique and permanent identifier code which identifies the data processing system and the object. The system uses a protection technique to prevent unauthorized access to objects by users who are identified by a subject number which identifies the user, a process of the system for executing a user's procedure, and the type of operation of the system to be performed by the user's procedure. An access control list for each object includes an access control list entry for each subject having access rights to the object and means for confirming that a particular active subject has access rights to a particular object before permitting access to the object. The system also includes stacks for containing information relating to the current state of execution of the system.

Assignee:

Data General Corporation - Westboro MA

International Classification:

G06F 934
G06F 704

US Classification:

364200

Abstract:

A digital computer uses a memory which is structured into objects, which are blocks of storage of arbitrary length, in which data items are accessed by descriptors which for a desired data item specify the object, the offset into that object, and the length of the data object. The computer system of the present invention further provides the ability to execute any of a plurality of dialects of internal instructions, the repertoire of such dialects being virtually infinite, since there is the ability to load a supporting microcode during operation as needed.

International Classification:

G06F 910

US Classification:

364200

Abstract:

A digital computer system having a memory system organized into objects for storing items of information and a processor for processing data in response to instructions. An object identifier code is associated with each object. The objects include procedure objects and data objects. The procedure objects contain procedures including the instructions and name tables associated with the procedures. The instructions contain operation codes and names representing data. Each name corresponds to a name table entry in the name table associated with the procedure. The name table for a name contains information from which the processor may determine the location and the format for the data (e. g. , an operand) represented by the name.
