    摘要: In the digital computer system of the present invention, data items called immediate names represent other data items. The immediate name specifies either the address of the represented data item or the address of a pointer to the represented data item. Each immediate name contains a base address specifier specifying one of a set of architectural base addresses, an indirection specifier specifying whether the immediate name specifies the address of the represented item or the address of a pointer to the item, and a displacement from the specified architectural base address. The architectural base addresses are contained in registers accessible to a processor in the digital data processing system. The registers are loaded only when the processor preforms a call operation or a return operation. When the immediate name specifies the address of the represented item, the processor produces the address by combining the displacement specified in the displacement specifier with the architectural base address indicated by the base address specifier. When the immediate name specifies the address of a pointer to the represented item, the processor combines the specified displacement with the specified base address to obtain the address of the pointer, fetches the pointer into memory, and produces the address of the represented item from the pointer.

    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.

    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.
