Abstract: Systems and methods are disclosed for editing metadata for data objects on a data storage device, which may be configured to identify data objects that have been modified and may be associated with storage locations of a file system. The data storage device may also be configured determine whether a first period of time has elapsed and may further be configured to determine whether a second period of time has elapsed or whether a threshold number of data objects in the file system have been modified in response to a first determination that the first time period has elapsed. The data storage device may further be configured to edit a set of metadata for a set of data objects in response to a second determination that the second period of time has elapsed or the threshold number of data objects in the file system have been modified.

Abstract: Aspects for increasing efficiency of memory accesses during graphics rendering are provided. A preferred method aspect includes providing a plurality of memory banks for data, and decoding input signals that indicate accessing of at least one of the plurality of memory banks for a desired plurality of words of data. The method further includes splitting data access across the plurality of memory banks to allow parallel selection of an output from at least one of the plurality of memory banks as the desired plurality of words of the data, wherein latency of data access is amortized.

Abstract: A pattern recognition system classifies images of patterns in which the definition of individual features of the pattern may have become blurred. The image is segmented into pieces of arbitrary size and shape, and various combinations are examined to determine those which represent the most likely segmentation of the pattern into its individual features. These individual features are then classified, according to known techniques. Through the use of a second order Markov model, not all possible combinations of pieces need to be examined, to determine the best ones. Rather, the examination of various combinations is limited in accordance with previously determined information, to thereby render the process more efficient. By combining multiple, independently determined probabilities, the accuracy of the overall operation is enhanced.
