| 20110006853 | MULTI MODE MODULATOR AND METHOD WITH IMPROVED DYNAMIC LOAD REGULATION - A dual mode modulator is proposed for driving a power output stage having a serial connection of high-side power FET and low-side power FET. The dual mode modulator includes a PWM modulator operating under a PWM-frequency and a PFM modulator for controlling the power output stage. To improve the dynamic load regulation of the dual mode modulator, a dynamic frequency booster can be added to the dual mode modulator to boost up the PWM-frequency from its normal operating frequency during a PFM-to-PWM mode transition period. Secondly, a dynamic slew rate booster can be added to boost up an error amplifier slew rate of the PWM modulator from its normal operating slew rate during the mode transition period. Thirdly, a dynamic turn-off logic circuit can be added to turn off the low-side power FET during the mode transition period. | 01-13-2011 |

| 20100131911 | Method and system for High Speed and Low Memory Footprint Static Timing Analysis - The invention provides a method and system for performing Static Timing Analysis on SoC (System on a Chip) designs. The invention solves a longstanding problem with timing analysis of designs, namely, the ability to multi-thread the design under analysis. The invention provides for slicing a design into levels, further decomposing each level into gates, and the multi-threaded processing of gates so that the solution of large design analysis is generated significantly faster than current approaches. Further, the invention provides that only one level exists in the RAM at any time. Once the arrival time on the level is computed, the data is saved to disk immediately. Because the memory footprint is sub-linear to the size of the design, entire system-on-a chip designs may be nm on inexpensive, off-the-shelf hardware. | 05-27-2010 |

| 20090018989 | USING SQL EXTENSIBILITY FOR PROCESSING DYNAMICALLY TYPED XML DATA IN XQUERY QUERIES - XQuery queries that include functions that operate on dynamically typed XML data are rewritten into compilable SQL constructs. XML data that is dynamically typed is XML data for which a specific XML data type cannot be determined at compile time and in fact may vary. In general, XQuery queries are rewritten into SQL queries that use SQL constructs in lieu of XQuery constructs. The SQL constructs include an “SQL polymorphic function” that is defined or recognized by a database system as valid syntax for an SQL query. The rewritten query applies the XML data to the SQL polymorphic function, but the XML data has been typed as XMLType, a data type recognized by SQL standards. | 01-15-2009 |

Such a reference is used to determine, for example, whether the corresponding node comes logical before, after, or is the same as another node. An SQL/XML query that includes a reference-based operator may be the original query, or may be generated (e.g., rewritten) from a non-SQL/XML query, such as an XQuery query. One or more physical rewrites may be performed on the SQL/XML query, depending on how the XML data is stored and/or whether an XML index exists for the XML data. | 06-18-2009 |
