    摘要: A digital integrating clock extraction technique for communication systems and information and data processing systems having high jitter and/or noise is disclosed. The technique is based on the integration and periodic analysis of a plurality of sorted data edge transitions of a received serial data stream. A retiming clock phase is selected from a plurality of locally generated clock signals of different phase. The retiming clock selection is preferably reevaluated after N data edge transition sorts. The resultant data edge histogram can be cumulative of all sorted transitions or merely cumulative of the last N sorted transitions. Corresponding methods and apparatus are described.

    摘要: A multi-system interconnect facility in which each central processor complex in the system has an assigned storage space for each other central processor complex in the system for use in communicating with each other central processor complex. The allegiance or association of systems to particular storage spaces is established when each system is initialized and enables a simple consisting primarily of instructions for moving control and data blocks between the program addressable space and the hardware addressable space.

    摘要: A self-timed interface (STI) in which a clock signal clocks bit serial data onto a parallel, electrically conductive bus and the clock signal is transmitted on a separate line of the bus. The received data on each line of the bus is individualy phase aligned with the clock signal. The received clock signal is used to define boundary edges of a data bit cell individually for each line and the data on each line of the bus is individually phase adjusted so that, for example, a data transition position is in the center of the cell.

    摘要: Calibration loops for a delay line (12'), for example, for digital phase locked logic circuitry for use in ascertaining the phase offset between a data signal and a local clock (10) and to produce a series of phase shifted clocks (f(i)'), are described. The calibration loops include a phase detector (14) coupled to receive as a first input the local clock applied to the delay line and as a second input the delay clock (f(n)') produced by the nth delay element (D v ) of an n element delay line. At least one of the delay elements (D v ) of the delay line is a variable delay element. The detector outputs a phase difference signal derived from the clocks applied at the first and second inputs. Control circuitry receives the phase difference signal from the detector and produces therefrom a corresponding control signal (CONTROL) which is applied to the at least one variable delay element to vary the delay through the delay line. Specific control circuitry embodiments are provided in the disclosure.
