    摘要： Several circuits and methods implemented to perform signal quality estimation and control are disclosed. In an embodiment, a method of signal quality estimation includes generating a demodulated signal associated with a radio signal. Information associated with a quality of the demodulated signal is accessed. Further, a value of radio frequency signal-to-noise ratio (RF-SNR) for the radio signal based on the information is estimated. Estimating the value of RF-SNR facilitates in signal quality estimation of the radio signal and control of the demodulated signal.

    摘要： A method of constructing a hierarchical database from an initial plurality of rules. A first rule of the initial plurality of rules is added to: a first sub-database if a first bit of the rule is a logic ‘0’ value; a second sub-database if the first bit is a logic ‘1’ value; or a third sub-database if the first bit is in a masked state, ‘X’, indicating that the first bit may be either a logic ‘1’ or a logic ‘0’ value.

    摘要： A packet classification device includes a CAM device, an SRAM device, and a control circuit that controls and coordinates the operations of the CAM and SRAM devices. For some embodiments, a first CAM block stores unique entries for each packet header field, a RAM block coupled to the first CAM block stores field labels for the unique packet header fields, a second CAM block stores group labels consisting of unique combinations of concatenated field labels, and a second RAM block coupled to the second CAM block stores a group identification (ID) for each group label, wherein each group ID identifies a corresponding one of the groups of rules.

    摘要： A search tree embodying a plurality of signatures to be compared with an input string of characters and including a number of branches of sequential states originating at a root node, wherein each state comprises a state entry including a failure transition and one or more success transitions, is optimized by selecting a failure size parameter indicating a minimum number of characters to be traversed on the failure transitions and selectively modifying the search tree to create a modified search tree for which all failure transitions to non-root states are characterized by the selected failure size parameter.

    摘要： Polymer blends comprise at least an ethylene/α-olefin interpolymers and at least one polyolefin. The polyolefins can be homopolymers or interpolymers and have a melt strength of at least about 6 cN. The ethylene/α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. The polymer blends can be profiled extruded to make profiles, gaskets, and other products.
