    摘要： On-the-fly error correction is provided using syndromes of a codeword encoded on data storage media. First and second syndromes are generated and a variable prescaler prescales the second syndrome by a field element to produce a prescaled second syndrome where the field element is variable. The error value is determined based on the first syndrome, and the error location is determined based on a comparison between the error value and the value of the prescaled second syndrome. The error value located at the error location is then corrected.

    摘要： On-the-fly error correction is provided by using the remainder from division of the encoded codeword by its generator polynomial to look up error values and locations in a memory. Alternatively, the syndromes are so employed. The values in the memory are predetermined and preassociated with each remainder or syndrome set. Alternatively, syndrome S.sub.0 directly yields the error value.

    摘要： Methods and apparatus for switching Fibre Channel Arbitrated Loop Systems is provided between a plurality of Fibre Channel Loop devices. In one aspect of the invention, the system switches based at least in part on arbitrated loop primitives. An exemplary interconnect system may include a first port and a second port, both including port logic to monitor certain arbitrated loop primitives, a connectivity apparatus, a route determination apparatus including a routing table consisting of ALPA addresses and their associated ports, the route determination apparatus coupled to each port and the connectivity apparatus, where the connectivity apparatus creates paths between the ports based on arbitrated loop primitives. In one embodiment, the connectivity apparatus is a crossbar switch. Examples of the arbitrated loop primitives that cause the switch to create paths between ports includes one or more of the following: ARB, OPN and CLS. In yet other aspects, the system ensures device access fairness through one or more techniques, including a rotating priority system, a counter to count the number of OPNs, especially sequential OPNs, and/or priority based on port type. Device zoning may be implemented. In one implementation, the system includes trunking such that frames may be transferred on multiple ports.

    摘要： Methods and associated hub arrangements are described for use in diagnosis and recovery in high performance digital loops such as, for example, those seen in Fiber Channel systems. In one system having a hub configured for interconnection of a plurality of stations as part of a digital system such that digital data flows between the stations based on operational status of the system, an arrangement forms part of the hub which arrangement is connectable at points within the hub and between at least two different pairs of the stations for monitoring certain characteristics of the data in a way which provides for non-invasive identification of one or more conditions related to the operational status of the system.

    摘要： Electronic circuitry for improving the speed and accuracy of shifting the magnetic heads of a disk memory from one to another track cylinder. Head velocity is measured with great accuracy by measuring the servo head transit time between adjacent tracks of the servo disk. A microprocessor controller in conjunction with preferred velocity profile data stored in a read only memory provides a control signal to the linear motor control causing the head arm velocity to follow the preferred velocity profile with excellent precision.

    摘要： Text messaging between cell phones, computer applications, and/or other communication devices has become a common means of communication. Because of the prevalence of text messaging, robust text message processing may be facilitated through text messaging pipelines. Accordingly, as provided herein, a text messaging pipeline may be configured according to a pipeline module list. The pipeline module list may be constructed through an online service wherein predefined pipeline modules and/or user defined pipeline modules may be selected to create the pipeline module list. The configured text messaging pipeline may provide customized text message processing. For example, a user may select a spam filter, a translator, and/or other pipeline modules to configure a text messaging pipeline. Text message workflow (e.g., SMS messages that are sent and/or received by a computer application associated with the text messaging pipeline) may be processed through the text messaging pipeline.
