Abstract: A device includes a first and a second stage round robin arbitrations. The first stage receives request signals and selects a subset the request signals. Each request signal is associated with whether a component is requesting access to a common resource. The second stage receives the selected subset and grants access to the common resource to each request signal of the selected subset that is requesting access, in a round robin fashion. The second stage outputs an enable signal to the first stage when the selected subset is processed. The first stage selects another subset and transmits the selected another subset to the second stage for round robin processing thereof. The process is repeated until all subsets with at least one request signal to access the common resource is processed and granted access in a round robin fashion.

Abstract: An entirely automated system for the interpretation of the field layout for multi-field files uses a rich contextual framework constructed by the interaction of three subsystems to provide a holistic view of the contexts of a structured data file as defined by the location and data type of each field. The roles of each of the subsystems are (1) the determination of the file's metadata and positions of the different data fields; (2) the use of fallible oracles (i.e., no oracle must be capable of identifying the type for every record) to provide a set of interpretations of the fields at several levels; and (3) the accurate determination of the location and specific data type for each field without the necessity to interpret every record correctly, even in the presence of ambiguity of data. The system may operate on both delimited and fixed-width structure files.

Abstract: Identifying files that do not deduplicate well in a storage system with deduplication facilitates optimizing storage capacity by moving the identified files to less expensive storage without deduplication. Any set of files can be examined to remove files that are identified as files that do not deduplicate well. The process of identification includes arranging the files in a predefined order and using bitmap representations of the unique segments in the files to determine a count of different segments in neighboring next files compared to the previous files, and removing from deduplication any next files that exceed a difference threshold. The bitmap representations of the files allows the identification processes to be performed efficiently for large datasets. Any over-identification of files is minimized by repeating the identification processes on the set of files after arranging them in the reverse order.
