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 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 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.

摘要： A digital computer system in which data storage is referred to by a descriptor comprising an object number denoting a variable-length block of storage, an offset indicating how far into that block a desired data item begins, and a length field denoting the length of the desired data item. Separate means exist for manipulating each of the three descriptor portions, thus facilitating repetitive operations on related or contiguous operands. Various levels of microcode control are included. Each level of microcode control has its own stack, facilitating interrupts between levels. Stacks are duplicated in "secure stacks" in memory to protect against loss of state data from the stacks.

摘要： A method for executing call and return instructions in a digital computer system operating under control of microcode. The microcode may specify calls to and returns from sequences of microinstructions. A call microinstruction sequence corresponds to the call instruction. The call microcode in turn calls other microinstruction sequences for deriving pointers representing the location of the called procedure and of arguments from operands in the call instruction. As the call microcode obtains each argument pointer, it places the pointer on the stack. After it has obtained all of the argument pointers, it passes the pointer to the called procedure and a pointer to the argument pointers to a general call microinstruction sequence. That microinstruction sequence locates the called procedure, makes a new frame including the argument pointers, and saves the state necessary to resume execution of the call microinstruction sequence itself. It then obtains the state necessary to commence execution of the called procedure and causes execution of that procedure to commence. The microcode corresponding to the return instruction restores both the state necessary to resume execution of the calling procedure and the state necessary to resume execution of the call microinstruction sequence. When it resumes execution, the call microinstruction sequence completes the return operation.

摘要： Systems and method for resolving unresolved pointers in digital computer systems. In unresolved pointers, addresses are represented by means of data items from which the addresses may be derived. The unresolved pointer is resolved when the represented address is derived from the data items. One such system includes the unresolved pointers and procedures for resolving the unresolved pointers in the digital computer system's memory and apparatus in the digital computer system's process which operates under control of pointer translation microcode to translate pointers into represented addreses and under control of call-return microcode for invoking procedures from microcode. The pointer translation microcode responds to an unresolved pointer by causing the call-return microcode to invoke the procedures for resolving the unresolved pointer. Using the data items in the unresolved pointer, the procedures derive the represented address and return it to the pointer translation microcode. Another such system includes an associated address table which associates an unresolved pointer with its represented address and associated pointer fault procedures. Here, the pointer translation microcode responds to the unresolved pointer by searching the table for an entry containing the unresolved pointer. If there is such an entry, the pointer translation microcode obtains the represented address from the table. If there is not, the pointer translation microcode causes the call-return microcode to invoke the associated pointer fault procedures, which resolve the unresolved pointer and place the represented address in the associated address table. A third such system combines the first two systems. Details of the systems and methods of resolving unresolved pointers are also disclosed.
