  • Publication number: 20070159224
    Abstract: A completely differential approach to correcting duty-cycle distortions of a differential clock signal propagating through a differential amplifier. A duty-cycle distortion correction (DCDC) differential amplifier circuit/device is provided with a differential amplifier whose output wires are coupled to a correction circuit. The correction circuit comprises a differential low pass filter and a differential correction amplifier. The differential correction amplifier's output is dotted back into the output of the amplifier. The differential output of the amplifier is passed through the low pass filter, which provides differential DC output signals that triggers respective correction amplifier transistors to generate an inverted correction current that is added back to respective differential output pulse. The DCDC differential amplifier provides a completely differential approach to correction of duty-cycle distortions within the differential output.

  • Patent number: 7213014
    Abstract: A database operation mechanism includes the capability of specifying a predefined database operation as a source of data for a different database operation. When the different database operation needs to be performed, the database operation mechanism determines whether the different database operation can use a predefined database operation as a data source. If so, the predefined database operation is specified as the source of data for the different database operation. If the different database operation cannot use a predefined database operation as a data source, the database operation mechanism determines whether the different database operation can use a modified form of a predefined database operation as a data source. If so, the different database operation may use the modified predefined database operation as a source of data.

  • Patent number: 7007099
    Abstract: An HDLC formatter and a message processing core exchange messages over a high speed message exchange interface. The interface includes a memory shared by the HDLC formatter and the message processing core. A handshaking arrangement is used to coordinate message storage and retrieval in the shared memory by the HDLC formatter and the message processing core with minimal utilization of processing resources of the message processing core. This handshaking coordination, together with the use of a message buffer accessed by the HDLC formatter to buffer channelized messages exchanged with the message processing core, facilitates message processing on multiple serial links (e.g., 3) over multiple timeslots (e.g., 256).

  • Publication number: 20040190724
    Abstract: A global key control mechanism provides a single point of overall control for key generation, but portions of the key generation and/or allocation tasks may be delegated to client computer systems, thereby reducing network traffic. The global key control mechanism may download a client key generation mechanism on one or more client computer systems, and may allocate a block of keys to the client key generation mechanism. Requests for keys may then be routed to the client key generation mechanism, which can generate and/or allocate keys within the block of keys that the global key control mechanism allocated to it. When the block of keys is used up, the client key generation mechanism may request another block from the global key control mechanism. The preferred embodiments also include the capability of downloading a client key generation mechanism with an associated block of keys once the requests from one or more client applications exceed a predetermined threshold.
