摘要： A means and method for testing high speed phase locked loops (13) in an integrated circuit (12) at a test frequency lower than the operation speed of the phase locked loop (13). A test circuit portion (10) repeatedly tests for a zero level (42) of a recover clock signal (34) from the phase locked loop (13) and a latching flip flop (26) is set to provide a lock indication output (30) as long as repeated samples, taken at a test time (38) continue to indicate a zero level (42) of the recover clock signal (34). The test time (38) is the leading edge (40) of a reference clock signal (36) provided from an external source at a reference clock input (28) to the integrated circuit (12).

摘要： A wrap back test system and method for providing local fault detection within a section of an integrated I/O interface core device on an integrated circuit is disclosed. The system and method of this invention is suitable for use in any I/O interface having both a transmitter and a receiver section. The wrap back of input test data, prior to reformatting for transmission, to the receiver's data alignment stage permits fault detection within the core of an integrated I/O interface. By illustration, in a serializer/deserializer I/O, the wrap back of alignment pattern encoded parallel data, prior to serialization, to the receiver's data alignment stage permits identifying faults in just this portion of the I/O transceiver. The wrap back test system and method of this invention permits fault isolation of within the boundaries of the I/O core and independent of external logic or testers.

摘要： A test method and means for in integrated circuit (10) having asynchronous communication capabilities including a transmitter (12) and a receiver (14). A pattern generator (24) is provided for generating patterns directly from within the integrated circuit (10). In the best presently known embodiment, a serializer (16) provides a serial output (20) and a deserializer (18) processes a serial input (22) into a parallel signal and provides the parallel signal to a receiver (14). The pattern generator (24) is preprogrammed to provide a parallel data pattern which can optionally and intermittently be provided to the transmitter (12) in a test mode (44). In the test mode (44), signal is routed from the serializer (16) directly to the deserializer (18) via an external loop back path (34) or an internal alternative loop back path (34a). When in the test mode, comparison unit (38) internally generates a pattern identical to that produced by the pattern generator (24) and locks onto signal received from the receiver (14) to perform a functional test (54) and an optional parametric test (58).

摘要： The present invention provides improved methods and devices for managing network congestion. Preferred implementations of the invention allow congestion to be pushed from congestion points in the core of a network to reaction points, which may be edge devices, host devices or components thereof. Preferably, rate limiters shape individual flows of the reaction points that are causing congestion. Parameters of these rate limiters are preferably tuned based on feedback from congestion points, e.g., in the form of backward congestion notification (“BCN”) messages. In some implementations, such BCN messages include congestion change information and at least one instantaneous measure of congestion. The instantaneous measure(s) of congestion may be relative to a threshold of a particular queue and/or relative to a threshold of a buffer that includes a plurality of queues.

摘要： Embodiments of the present invention are directed to methods and systems for determining unknowns in rating matrices. In one embodiment, a method comprises forming a rating matrix, where each matrix element corresponds to a known favorable user rating associated with an item or an unknown user rating associated with an item. The method includes determining a weight matrix configured to assign a weight value to each of the unknown matrix elements, and sampling the rating matrix to generate an ensemble of training matrices. Weighted maximum-margin matrix factorization is applied to each training matrix to obtain corresponding sub-rating matrix, the weights based on the weight matrix. The sub-rating matrices are combined to obtain an approximate rating matrix that can be used to recommend items to users based on the rank ordering of the corresponding matrix elements.

摘要： Various improvements are provided for prior art policing methods, including token bucket methods and virtual time policing methods. Some preferred methods of the invention involve assigning a non-zero drop probability even when the packet would otherwise have been transmitted according to a prior art policing method. For example, a non-zero drop probability may be assigned even when there are sufficient tokens in a token bucket to allow transmission of the packet. A non-zero drop probability may be assigned, for example, when a token bucket level is at or below a predetermined threshold or according to a rate at which a token bucket is being emptied. Some implementations involve treating a token bucket as a virtual queue wherein the number of free elements in the virtual queue is proportional to the number of remaining tokens in the token bucket. Such implementations may involve predicting a future virtual queue size according to a previous virtual queue size and using this predicted value to calculate a drop probability.
摘要翻译：为现有技术的管理方法提供了各种改进，包括令牌桶方法和虚拟时间监管方法。本发明的一些优选方法涉及分配非零丢弃概率，即使当根据现有技术的监管方法将分组以其他方式传输时也是如此。例如，即使在令牌桶中有足够的令牌来允许分组的传输，也可以分配非零丢弃概率。例如，当令牌桶级别等于或低于预定阈值时或者根据令牌桶被清空的速率时，可以分配非零丢弃概率。一些实现涉及将令牌桶视为虚拟队列，其中虚拟队列中的空闲元素的数量与令牌桶中剩余令牌的数量成正比。这样的实现可以涉及根据先前的虚拟队列大小预测未来的虚拟队列大小，并且使用该预测值来计算丢弃概率。
