    摘要: A hardware monitor interface unit (HMIU) is coupled to a data processing system. Programmable hit matrices (PHM's) in the HMIU store information which is compared with information from the data processing system. The PHM's generate "hit" signals indicating comparison. These "hit" signals are received by monitors coupled to the HMIU which are used to compile the data processing system performance data. Appartus in the HMIU generates clocking signals enabling the information to be received by the HMIU and generates strobing signals to be used for timing the "hit" signals and other control signals received by the monitors.

    摘要: A monitor interface unit couples a monitor to a data processing system which includes a central processing unit (CPU). The monitor generates data for determining the performance of the data processing unit. The monitor interface unit includes apparatus for stopping the CPU clock during a particular CPU operation and then slowing down the CPU clock rate.

    摘要: A hardware monitoring interface unit (HMIU) is coupled to a data processing unit and receives all information transferred between subsystems of the data processing unit. Programmable hit matrices (PHM's) include input latches for receiving the information, memory circuits for storing binary ONE's in locations addressed by predetermined portions of the information and output latches for storing the binary ONE's or "hit" signals read from the memory circuits. The "hit" signals are plug-wired into logic circuits and counters in a monitor to collect statistical data.

    摘要: A data processing system includes a number of subsystems, all coupled in common to a system bus. Also coupled to the system bus is a hardware monitor interface unit (HMIU) for receiving all information transferred between subsystems. The HMIU includes programmable hit matrices (PHM's). The PHM's include memory circuits which generate "hit" signals when predetermined information addresses the memory circuits. The "hit" signals or binary ONE's are loaded into the memory circuits during a load mode during which system bus information specifically addressing the HMIU is received on two system bus cycles for each address location of the memory circuit. The data bus contains the memory circuit address during the first system bus cycle and the data during the second data bus cycle. An address bus signal identifies the cycle.

    摘要: Computer addressing hardware and a method of address development which utilizes the concept of a segment as the unit of addressability is disclosed.The fundamental vehicle for addressing is the segment wherein an address space is defined for a process and is included as part of the controlled information of the logical processor (the collection of hardware resources and control information necessary for the execution of a process.) The address space defines a predetermined number of different segments in which instructions can access operands. Within a segment, access is by relative location to the beginning of the segment, and is computed during address development. Any attempt to access information beyond the upper bound of the segment is detected by hardware and an exception condition occurs. An instruction may access an operand either directly or indirectly via a data descriptor, wherein an address syllable in the instruction is used for reference, and specifies whether reference is direct or indirection is to be preferred. The address syllable specifies a base register which defines the segment to be referenced and an offset within the segment. The address syllable also contains a displacement from this defined base. Address development hardware obtains the absolute address of the beginning of the segment, adds to this; the offset defined in the base registers, the displacement defined by the instructions, and if required the contents of an index register. This summation produces the required absolute address.
