摘要： 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. A system aspect for improving data transfer from memory to a texture mapping unit includes a plurality of cache banks for storing texel data, a bank decode unit coupled to the plurality of cache banks for decoding a plurality of input signals indicative of selection of texel data from one or more of the plurality of banks, and selection control logic for receiving decoded address data from the bank decode unit and controlling selection of the plurality of cache banks to retrieve the texel data for output to the texture mapping unit.

摘要： 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.
摘要翻译：模式识别系统对图案的各个特征的定义可能变得模糊的图案进行分类。图像被分割成任意尺寸和形状的片段，并且检查各种组合以确定代表将图案最可能地分割成其各个特征的组合。然后根据已知技术对这些单独的特征进行分类。通过使用二阶马尔可夫模型，不需要检查所有可能的零件组合，以确定最佳的。相反，根据先前确定的信息来限制各种组合的检查，从而使得过程更有效率。通过组合多个独立确定的概率，增强了整体操作的准确性。
