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. Addresses are independent of system physical configuration and, as particularly described withreference to the invention herein, indentify locations of object information to be accessed by utilizing 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.

A system for modifying the manner in which a processor in a digital computer system responds to operation codes in certain instructions. All instructions to which the system responds have operation code syllables containing an operation code and an operation code modifier. In instructions having certain operation codes, the operation code modifier contains a value which modifies the manner in which the processor responds to the operation code. When the processor receives an instruction having such an operation code, a part of the processor which is responsive to the operation code modifier employs the value in the operation code modifier to modify the interpretation of the instruction by the processor. The manner in which the value is employed depends on the operation code. Several uses of the operation code modifier are disclosed.

G06F 922

364200

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.

The processor of the present invention can execute any of a plurality of dialects of "S-Language" instructions. S-Languages are of a higher order than typical machine languages but of a lower order than the user's own high order language. They can be tailored for compatibility with user high order languages. Each instruction of a particular S-Language is interpreted by a sequence of microinstructions. In the processor of the present invention, dispatching to the microinstruction sequencer is controlled jointly by the instruction bit pattern and the current contents of a dialect register. Each procedure to be executed carries with it information from which the appropriate contents of the dialect register may be determined. Thus, the processor of the present invention can always operate as an effective optimum processor for executing the procedure regardless of the source language chosen for writing that procedure.

A data processing system which includes a memory and a processor comprising at least two execution units. The system further includes a microcode control unit for storing sequences of microinstructions and an execution microinstruction stack containing at least one stack frame containing the machine state of a first execution unit when the execution of a microinstruction has been interrupted. A memory microinstruction stack is provided to store a plurality of stack frames, stack frames being transferrable between the execution microinstruction stack and the memory microinstructiion stack. The microcode control unit contains sequences of monitor microinstructions and has associated with it a minotor microinstruction stack for storing the machine state of the first execution unit when the execution of a monitor microinstruction has been interrupted. A second execution unit for executing primarily arithmetic microinstructions includes an execution storage unit containing the current machine state of the second execution unit and an arithmetic stack which stores the machine state of the second execution unit when it has executed a previous arithmetic microinstruction. The memory includes a memory arithmetic stack containing further arithmetic stack frames, stack frames being transferrable between the execution storage unit and the memory arithmetic stack.

A speedometer scale conversion kit and method of utilization of the components of such kit comprises the present invention. The conversion kit is composed of a step-by-step instructional sheet, a decal card and a cardboard strip having printed guide indicia. The instruction sheet provides the step-by-step method for forming the cardboard strip into a ten kilometer gauge, using the gauge to measure off and mark ten kilometer spacings on the transparent face cover of the speedometer, and for then removing and placing the appropriate kilometer number decal on the premarked face of the speedometer.
