Serialization logic selects one of the target addresses and determines which of the requests specify the selected target address. All such requests are allowed to proceed in parallel, while other requests are deferred. Deferred requests may be regenerated and processed through the serialization logic so that a group of requests can be satisfied by accessing each different target address in the group exactly once. |

Zero-copy data sharing by cooperating asymmetric coprocessors
One embodiment of the present invention sets forth a technique for reducing the copying of data between memory allocated to a primary processor and a coprocessor is disclosed.

Removal of the need for explicit primary processor memory to coprocessor memory and coprocessor memory to primary processor memory copies improves the performance of the application and reduces physical memory requirements for the application since one portion of memory is shared rather than allocating separate private portions of memory. |

The second WSO request identifies the same cache line as to be written during the subsequent WSO transaction. In response to receiving the second WSO request, the system sends an abort signal to cause the processing subsystem to abort the WSO transaction. |

However, if a collision exists, the write access is re-mapped to a spare bank identified by the write instance information, allowing simultaneous read and write. Both read and write mapping memories are updated to reflect any re-mapping. |

Combined floating point adder and subtractor
Circuitry (fixed or configured in a programmable device) for performing floating point addition and subtraction uses approximately the same resources as required for either operation separately. The circuitry is based on a recognition that when adding or subtracting two numbers, the two resulting mantissa values will be two out of three possibilities, and will involve either a one-bit shifting operation, or a shifting operation involving a large number of bits. Therefore, one mantissa path—a subtraction path—can be provided with full add/normalize/round circuitry, while a second mantissa path—an addition path—can be provided with a simple one-bit shifter and simplified rounding circuitry. Because the input numbers are signed, the “addition path,” which only adds the mantissas, may provide the mantissa for the subtraction result, depending on the signs of the input numbers. Similarly, the “subtraction path” may provide the mantissa for the addition result. |

Structured cross-lingual relevance feedback for enhancing search results
A “Cross-Lingual Unified Relevance Model” provides a feedback model that improves a machine-learned ranker for a language with few training resources, using feedback from a more complete ranker for a language that has more training resources. The model focuses on linguistically non-local queries, such as “world cup” (English language/U.S. market) and “copa mundial” (Spanish language/Mexican market), that have similar user intent in different languages and markets or regions, thus allowing the low-resource ranker to receive direct relevance feedback from the high-resource ranker. Among other things, the Cross-Lingual Unified Relevance Model differs from conventional relevancy-based techniques by incorporating both query- and document-level features. More specifically, the Cross-Lingual Unified Relevance Model generalizes existing cross-lingual feedback models, incorporating both query expansion and document re-ranking to further amplify the signal from the high-resource ranker to enable a learning to rank approach based on appropriately labeled training data. |

Correction of non-uniformity of response in sensor arrays
A microbolometer comprises an array of sensor elements or ‘pixels’ each individually responsive to generate an output indicative of the intensity of infrared radiation incident thereupon. In practice there are significant non-uniformities in the response of each pixel and further processing of the outputs must take place to generate an accurate image. These non-uniformities are dealt with by means of individual correction factors to be applied to the outputs of each pixel in the image. Commonly, the correction used provides a constant offset (1pt) and a linear gain correction (2pt). As the optimal values of these corrections drifts over time it is still necessary to provide further correction. In the present invention this is achieved by calculating one or more common scalar correction parameters that when applied to all of the individual correction factors before they are used to correct the output of the sensor elements will minimize the differences between the corrected outputs of adjacent sensor elements in the array when summed over a particular selection of sensor elements in the array. |

Cardio mapping system and method for cardio mapping
A method and system for determining the mechanism of cardiac arrhythmia in a patient is disclosed. The method basically entails measuring the impedance of cardiac tissue in a portion of the patient's heart using a catheter during an episode of supraventricular tachycardia to produce an iso-impedance map of that cardiac tissue on a video display and analyzing the pattern of the iso-impedance map to differentiate focal arrhythmia caused by a circumscribed region of focal firing and reentrant arrhythmia caused by a macroreentrant circuit.
