Abstract: A method and system for processing a request to retrieve data from a database is disclosed. The method of the present invention comprises receiving the request which comprises a function that processes at least one data item specified in the request, retrieving the at least one data item from a database, and invoking the function. When the function is invoked, at least one parameter comprising information related to the at least one data item is passed to the function. Thus, a function can be written independently of the data which they are called to process.

Abstract: A method and system for controlling concurrency of access to data in a database system, includes: partitioning a table in the database system into a plurality of partitions; receiving a request for access to data; determining a partition of the plurality of partitions that contains the data; determining if the data has been committed; and if so, avoiding locking the partition in response to the request. By avoiding locking the partition when the data has been committed, the number of partition locks that need to be requested from a local resource lock manager is reduced, improving performance.

Abstract: A method for operating plurality of DSL modem transmitters integrated within a circuit card. The method includes each DSL modem transmitter: generating a full power physical frame when the DSL modem transmitter is provided with data to transmit; generating a low power physical frame having a control channel signal component and no data; and selecting between the full power physical frame and the low power physical frame for transmission from the DSL modem transmitter, wherein selection of the low power physical frame for transmission from the DSL modem transmitter is based only on the DSL modem transmitter having no data to transmit. The method further includes limiting aggregate flow of data to the plurality of DSL modem transmitters such that a total power required by the plurality of DSL modem transmitters is held below a predefined target power level.

Abstract: Aspects of providing automatic adaptation to frequency offsets in high speed serial links are described. First signals for phase adjusts in a receiver link are adjusted by detecting trends in the first signals to generate second signals, the second signals improving a rate of compensation for the frequency offsets by the phase adjusts. An up/down counter is included for counting signals for phase adjustments by a clock-data-recovery loop of a serial receiver. An adder is coupled to the up/down counter and outputs accumulated data indicative of a trend in the phase adjustments. Combinatorial logic coupled to the adder adapts the signals based on the accumulated data.

Abstract: Reducing power consumption in latches and similar electronic devices. In one aspect, an apparatus for configuring power consumption of sequential logic includes a sequential logic device including a first latch, a second latch, and first and second enable inputs. The first enable input enables and disables the first and second latches, and the second enable input enables and disables the second latch and does not affect the first latch. The first enable input has an earlier required signal arrival time than the second enable input to be effective for a particular clock cycle. A circuit configures the sequential logic device at operating time to consume less power during a lower frequency of operation of the sequential logic device, and to consume more power during a higher frequency of operation.

Abstract: A method and system for providing a modular server-on-a-USB-flash-storage is disclosed. The server-on-a-USB-flash-storage is installed on a computing device. The method and system include providing USB interface logic, USB Local Control Program, a flash memory and a set of control button connectors, light emitting diodes (LED) connectors and a liquid crystal display (LCD) connector. The USB Local Control Program is coupled with the USB interface logic and the flash memory. The USB interface logic interacts with the computing device and allows the computing device to detect the server board. The USB Local Control Program boots up the server and prepares the computing device for use as the server. The flash memory stores a server image for the server, which is provided to the computing device using the USB Local Control Program. The control button connectors allow the server to be turned on, shut down gracefully, or restored to its initial state, by a single press of buttons connected to these connectors.
Abstract: A method for passing parameters of data structures where an API and corresponding stored procedures are at different version/release levels is provided. A received data structure is parsed for a version identifier of a caller. The parsed version identifier is compared to a stored procedure version identifier and a determination is made with regards to a data structure compatibility or a data structure incompatibility. If a data structure compatibility is determined, all received data structure elements are parsed. If, however, a data structure incompatibility is determined, only data structure elements known to both the caller and the stored procedures are parsed.
