    摘要: A plurality of trap save areas are linked to form a pool of such areas from which an area may be loaded with context from various sources in response to a trap condition, such as the addressing of unuseable memory, the loaded area unlinked from the pool, and various pointers changed to reflect such unlinking. The unlinked area is associated with the process which was executing at the time of the occurrence of the trap condition by effectively being coupled to the interrupt level of such process. Independent of the interrupt level, a trap handler routine, specific to the nature of the trap condition, is executed following which the unlinked area is returned to the pool and the various pointers changed to reflect such return.

    摘要: A final effective address of an operand is generated in a microprogrammed data processing system by use of a base address register which may include an unindexed address, an index register which may include an index address value, an instruction register which may include an instruction word, which instruction word provides control over the addressing of a control store dependent upon the state of a selected one of a plurality of test conditions. The addressed control store word provides signals for controlling the operation of the system, including the branching between such major operations as instruction fetching, addressing, reading, writing, and execution as well as branching between minor operations which are included in the major operations.

    摘要: A last-in, first-out register having multiple address input ports and capable of storing a plurality of addresses. Address loading operations are over-lapped with address reading operations to speed up the rate at which addresses may be stored in and retrieved from the register. When the register is full of addresses it provides an indication which permits: the addresses already stored in the register to be read out and stored in an external memory, then additional addresses to be stored in the register, and subsequently the addresses transferred to the memory for storage to be retransferred to the buffer address register for read out.

    摘要: What is disclosed is a time partitioned bus arrangement for use in a computer system wherein different circuits therein are interconnected by a plurality of busses and operation is such that information to be processed can be read out of one circuit, processed in some manner in another circuit, and the processed information be stored in the same or another circuit all within one cycle of a system clock in the computer system, and without the need for bus control circuits and bus interfaces in the circuitry connected to the busses. Some of the circuits have their input/output connected to only a single one of the busses, while other circuits have their input connected to one bus and their output connected to a different bus, and yet other circuits have either their input or output connected to one of the busses and their other input/output connected to circuitry external to the bus arrangement. Some of the processor circuits have a control lead input that is energized by the clock signal output from the system clock so that they accept information from one bus to which their input is connected during a first polarity portion of a clock cycle and return either unprocessed or processed information to another bus during a second polarity portion of a clock cycle.
