The switch can also be configured to determine an output buffer ratio in dependence upon at least an inbound data rate characteristic of the input port and an outbound data rate characteristic of the determined output port. The output port can be configured to commence onward transmission of the packet once a proportion of the packet conforming to the output buffer ratio has been written into the output buffer.

Abstract: A method and system for resource based authentication may include, in response to a client attempting to access a protected resource of a system, implementing resource based authentication. A policy agent may intercept the client access request and redirect it to an appropriate authentication gateway module based upon authentication polices. If the protected resource is not associated with any resource specific authentication technique, the policy agent may apply a default authentication technique. If, however, the protected resource is associated with a particular resource specific authentication technique, the policy agent may apply the resource specific authentication technique without applying the default authentication technique.

Abstract: The present disclosure describes a unique way for each of multiple processes to operate in parallel and use the same shared data without causing corruption to the shared data. For example, during a commit phase, a corresponding transaction can attempt to increment a globally accessible version information variable and store a current value of the globally accessible version information variable for updating version information associated with modified data regardless of whether an associated attempt by the corresponding transaction to modify the globally accessible version information variable was successful. As an alternative mode, a corresponding transaction can merely read and store a current value of the globally accessible version information variable without attempting to update the globally accessible version information variable before such use.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention enable a user to input data into a document having cells arranged in columns and rows. A first of the cells and a second of the cells each have an original content. The original content of the first cell is overridden with a first user inputted value. The cells are recalculated based on the first user inputted value. After recalculating the cells based on the first user inputted value, the original content of the second cell is overridden with a second user inputted value. The cells are recalculated based on the second user inputted value. The original content of the first cell is automatically restored based on a user input such that the second user inputted value is maintained in the second cell.

Abstract: A feedback module is defined to receive as input a set of data sample signals and a set of reference sample signals. Each of the data and reference sample signals is generated by sampling a differential signal having been transmitted through a FIR filter. The feedback module is defined to operate a respective post cursor counter for each post cursor of the FIR filter and update the post cursor counters based on the received sets of data and reference sample signals. Also, the feedback module is defined to generate a tap weight adjustment signal for a given tap weight of the FIR filter when a magnitude of a post cursor counter corresponding to the given tap weight is greater than or equal to a threshold value. An adaptation module is defined to adapt a reference voltage used to generate the reference sample signals to a condition of the differential signal.

Abstract: One embodiment of the present invention provides a system that asynchronously controls sending data items from a sender to a receiver. This system includes a set of sending FIFOs, a set of receiving FIFOs, as well as a shared data path between the sender and the receiver. The system also includes a set of control paths that operate in parallel between the sender and the receiver, wherein a given control path controls the transmission of data items between a corresponding sending FIFO and a corresponding receiving FIFO through the shared data path. The system further includes a round-robin scheduling mechanism which activates one control path at a time in a predetermined sequence. An activated control path asynchronously controls the sending of a data item from a corresponding sending FIFO to a corresponding receiving FIFO.

Abstract: An apparatus and methods for recovering a clock and a data stream from a source synchronous input data stream are disclosed. The apparatus comprises a filter, a decision feedback equalizer (DFE), a phase error detector, and a clock generator. The input data stream is coupled to the filter and the DFE. The DFE synchronizes the input data stream to a clock generated by the clock generator. A filter output and a DFE output are each coupled to the phase error detector. During an initialization period, the phase error detector conveys a phase error to the clock generator based on one or more phase error estimates of the filter output and during a period of steady-state operation, the phase error detector conveys a phase error to the clock generator based on one or more phase error estimates of the DFE output. The output of the DFE comprises a recovered data stream.

Abstract: Search queries to a search engine are collected over a period of time and used as a source of terms for selectively adding to documents. The terms may be added as meta-tags for enhancing information retrieval. Also, candidate terms may be submitted to the search engine and the most relevant documents retrieved. These documents, or portions thereof, are reviewed to determine if the content is substantially related to the term. If it is, the term is added to the document as a meta-tag and the search engine index is updated to reflect the addition. Employing this invention, search engine results will adapt to changes in usage of search terms.

Abstract: Method and apparatus for synthesizing multiple localizable file formats into a canonical format. Embodiments may provide a file format-independent localization mechanism that automates the extraction of localizable text content from localizable files of different file formats and generates translation kits formatted according to a canonical format. The generated translation kits may include localizable text content from the localizable files for which translations were not found in a translation database. The generated translation kits may be handed off to translators for translation of the localizable text content in the translation kits. The translated text content in the translation kits may then be imported into the translation database and merged by the localization mechanism into localized versions of the localizable files while preserving the original file structure of the files.

Abstract: One embodiment of the present invention provides a system that improves program performance by enregistering memory locations. During operation, the system receives program object code which has been generated for a given hardware implementation, and hence is optimized to use a specified number of registers that are available in that hardware implementation. Next, the system translates this object code to execute on a second hardware implementation which includes more registers than the first hardware implementation. The system makes use of these additional registers to improve the performance of the translated object code for the second hardware implementation. More specifically, the system identifies a memory access in the object code, where the memory access is associated with a memory location. The system then rewrites an instruction associated with this memory access to access the available register instead of the memory location.
