摘要： A digital computer system including a memory and a processor. The memory operates in response to memory commands received from the processor. Items of data stored in the memory include instructions to which the processor responds. Each instruction contains an operation code which belongs to one of several sets of operation codes. The meaning of a given operation code is determined by the operation code set to which the instruction belongs. Some of the instructions also contain names representing items of data used in the operation specified by the operation code. The processor includes an operation code decoding system which decodes the operation code as required for the instruction set to which it belongs, a name resolution system for deriving the address of the data item represented by a name from the name using an architectural base address contained in the name resolution system, and a control system which controls the operation of the processor. The processor performs a call operation and a return operation. Only the call operation and the return operation may change the current architectural base address. The memory further contains name table entries associated with the names. Each name table entry contains information used by the name resolution system when it resolves a name.

摘要： A digital computer system having a memory system organized into procedure and data objects, each having a unique identifier code and an access control list, for storing items of information and a processor for processing data in response to instructions. The instructions contain operation codes and names representing data. Each name corresponds to a name table entry in a name table which contains information from which the processor determines the location and the format for the data. The name table entry specifies a base address of one of a set thereof which change value only when a call or a return instruction is executed. A name interpretation system fetches a name table entry, calculates the base address and a displacement using the name table entry and the current architectural base address and adds the base address to the displacement to form the address of the data represented by the name.

摘要： 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 identification of information and an extremely large address space accessible and common to all such systems. Addresses are independent of system physical configuration. Information is identified to bit granular level and to information type and format. Protection mechanisms provide variable access rights associated with individual bodies of information. User language instructions are transformed into dialect coded, uniform, intermediate level instructions to provide equal facility of execution for all user languages.

摘要： 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 utilizes unique addressing mechanisms the addresses of which have object fields, offset fields and length fields for specifying the location and the total number of bits of an addressed 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 the 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.

摘要： A digital computer system having a memory system organized into objects for storing data and a processor for processing data in response to instructions. An object identifier and an access control list are associated with each object. The memory system responds to logical addresses for data which specify the object containing the data and the offset of the data in the object and to a current subject for which the processor is referencing the data. The memory system performs a memory operation for the processor only if the access control list for the object specified by the logical address allows the current subject to perform the desired memory operation. 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 operations 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 derive the logical address for the data represented by the name. The processor may then use the logical address to specify a memory operation on the data represented by the name.

摘要： 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 identification of information as objects and an extremely large address space accessible and common to all such systems. Addresses are independent of system physical configuration and, as particularly described with reference to the invention herein, identify locations of object information to be accessed by utlizing address formats which comprise an object field, offset field and a length field so that information can be identified to bit granular level and to information type and format. Arithmetic logic unit (ALU) means, also as particularly described with reference to the invention herein, include general register means having three vertically oriented parts for storing such respective fields. Such ALU means further include an ALU microinstruction stack means having at least one microinstruction stack frame for storing the state of execution of a microinstruction. A memory microinstruction stack is provided to store a plurality of microinstruction stack frames so that microinstruction stack frames can be transferred between the ALU and the memory microinstruction stacks. Protection mechanisms provide variable access rights associated with individual bodies of information. User language instructions are transformed into dialect coded, uniform, intermediate level instructions to provide equal facility of execution for all user languages. Operands are referred to by uniform format names which are transformed, by internal mechanisms transparent to users, into addresses.
