20100058146 | CHIEN-SEARCH SYSTEM EMPLOYING A CLOCK-GATING SCHEME TO SAVE POWER FOR ERROR CORRECTION DECODER AND OTHER APPLICATIONS - Chien search apparatus operative to evaluate an error locator polynomial having a known rank and including a sequence of terms for each element in a finite field whose elements correspond respectively to bits in each of a stream of data blocks to be decoded, the apparatus comprising a sequence of functional units each operative to compute a corresponding term in the sequence of terms included in the error locator polynomial, each term having a degree; and a power saving unit operative to de-activate at least one individual functional unit from among the sequence of functional units, the individual functional unit being operative, when active, to compute a term whose degree exceeds the rank. | 03-04-2010 |
20100131831 | LOW POWER CHIEN-SEARCH BASED BCH/RS DECODING SYSTEM FOR FLASH MEMORY, MOBILE COMMUNICATIONS DEVICES AND OTHER APPLICATIONS - A low power Chien searching method employing Chien search circuitry comprising at least two hardware components that compute at least two corresponding bits comprising a Chien search output, the method comprising activating only a subset of the hardware components thereby to compute only a subset of the bits of the Chien search output; and activating hardware components other than those in the subset of hardware components, to compute additional bits of the Chien search output other than the bits in the subset of bits, only if a criterion on the subset of the bits of the Chien search output is satisfied. | 05-27-2010 |
20120001778 | SYSTEM AND METHOD FOR MULTI-DIMENSIONAL ENCODING AND DECODING - A system and method for decoding multi-dimensional encoded data. A set of multi-dimensional encoded data may be received encoding each input bit in a set of input bits by multiple different component codes in multiple different encoding dimensions. The multi-dimensional data may potentially have errors. A map may be used to locate each set of intersection bits that encode the same input bit by multiple unsolved component codes. The unsolved component codes may be decoded using one or a plurality of tested error correction hypotheses that yields a decoding success, where each hypothesis correcting a different set of intersection bits for a different input bit. The successful hypothesis may be applied for correcting the multi-dimensional encoded data. | 01-05-2012 |
20120005554 | SYSTEM AND METHOD FOR MULTI-DIMENSIONAL ENCODING AND DECODING - A system and method for using a cyclic redundancy check (CRC) to evaluate error corrections. A set of data and initial CRC values associated therewith may be received. The set of data by changing a sub-set of the data may be corrected. Intermediate CRC values may be computed for the entire uncorrected set of data in parallel with said correcting. Supplemental CRC values may be computed for only the sub-set of changed data after said correcting. The intermediate and supplemental CRC values may be combined to generate CRC values for the entire corrected set of data. The validity of the corrected set of data may be evaluated by comparing the combined CRC values with the initial CRC values. | 01-05-2012 |
20120005560 | SYSTEM AND METHOD FOR MULTI-DIMENSIONAL ENCODING AND DECODING - A system and method is provided for decoding a set of bits using a plurality of hypotheses, for example, each independently tested on-the-fly. Initial bit states and associated reliability metrics may be received for the set of bits. A current hypothesis may be decoded for correcting the set of bits, wherein the current hypothesis defines different bit states and associated reliability metrics for the set of bits. If decoding the current hypothesis is not successful, a subsequently ordered hypothesis may be decoded, wherein the hypotheses are ordered such that their associated reliability metric is a monotonically non-decreasing sequence. Decoding may proceed iteratively until the current hypothesis is successful. | 01-05-2012 |

20090177698 | Client Access License Tracking Mechanism - A client tracking mechanism has a log file analysis routine that may generate two tables, one having a licensable entity designator and last logged off time, and the other having a current session designator. The first table may be aggregated by a server that may collect data from multiple client tracking mechanisms to determine a licensable entity's sessions across multiple servers. The client tracking mechanism may save and resume analysis from the last analyzed log file entry, and may be able to track sessions that are both shorter and longer than the time between each analysis. In many embodiments, a licensable entity may be a user or a device, when a license arrangement is configured in a per-user or per-device basis. | 07-09-2009 |
20110246913 | Automated User Interface Generator - A user interface may be selected for a system with hierarchical data types by traversing an inheritance tree to find a pre-defined user interface, or by automatically generating a user interface based on the type definition. The automatically generated user interface may include tabs or groupings for components of the data type that may be inherited from other data types. In some embodiments, portions of the automatically generated user interface may be obtained from other data types. | 10-06-2011 |
20110264703 | Importing Tree Structure - A set of structured data may be stored using a format file and a data file. The format file may contain a hierarchical structure in the form of classes and relationships, while the data file may store the instances of the data in a serialized form. The format file may include projection types as well as repeating or nested types. The data file may contain instances of the structured data in the form of rows, with commas or other delimiters separating the data items. The structure of the data file may be created by traversing the format file to create a fully populated list of data items representing the structured data. An application may read the format file and data file to import complex data types and populate instances of those data types. | 10-27-2011 |
20110289055 | Linked Databases - Several local databases may be linked together to form a large database. Each database may share a common type definition, but may contain only a portion of the large database. When a local database queries information from another database, the result may be stored locally using the type system. Across the entire database, items may be identified as their local or home database along with an identifier provided by that database. Cached information may be stored locally and may refer to the source for that information through the identifier. Once the cached information is present, queries that reference the record may be satisfied by the cached information. The cached information may be refreshed from the source database or may expire to avoid stale or changed data in the cache. | 11-24-2011 |
20120117498 | SECONDARY OUTPUT GENERATION FROM A PRESENTATION FRAMEWORK - A secondary output of a user interface created using a presentation framework may be created by making a clone of the user interface, then modifying the cloned user interface by expanding various components. The cloned user interface may also be configured to the output characteristics of the secondary output, which may be a printer or other hardcopy device. The user interface may be created with callbacks or other actions that may be executed when the cloned user interface is configured. The callbacks may cause certain user interface components to be changed on the cloned version of the user interface. | 05-10-2012 |

The cloned user interface may also be configured to the output characteristics of the secondary output, which may be a printer or other hardcopy device. The user interface may be created with callbacks or other actions that may be executed when the cloned user interface is configured. The callbacks may cause certain user interface components to be changed on the cloned version of the user interface. | 02-06-2014 |
