Abstract: A client-server relational database system, wherein data from the client computer is encrypted by the client computer and hosted by the server computer, the encrypted data is operated upon by the server computer, using one or more operators selected from a group of operators comprising: (a) inequality logic operators, (b) aggregation operators, and (c) wildcard matching operators, to produce an intermediate results set, the intermediate results set is sent from the server computer to the client computer, and the intermediate results set is decrypted and filtered by the client computer to produce actual results. The group of operators is limited because the encrypted results set, when decrypted, includes inaccuracies therein. The client computer applies a set of correction procedures to the decrypted results set to remove the inaccuracies therein.

Aspects of the invention include providing a set of candidate n-grams, each n-gram comprising a sequence of characters; identifying sample queries having character strings containing the candidate n-grams; and based on the set of candidate n-grams, the sample queries, database records, and an n-gram space constraint, automatically selecting, given the space constraint, a minimal set of an n-grams from the set of candidate n-grams that minimizes the number of false hits for the set of sample queries had the sample queries been executed against the database records.

Abstract: Routing systems and methods are provided having various strategies for optimizing and evaluating possible routes for netlist connections. In one embodiment, a data structure or matrix provides cost related data weighted to evaluate the impact proposed a connection or segment will have upon an attribute of interest such as, for example, speed, manufacturability or noise tolerance. This cost information can be related to terrain costs as well as shape costs to provide multidimensional cost information for connections. Processing such higher information cost data is made more efficient with an additive process that is less demanding than a computationally intensive iterative multiplication process. Various methods are also disclosed for shifting and adjusting routing grids to improve use of available space or reduce run time in routing.

Abstract: A processor for use in a router, the processor having a systolic array pipeline for processing data packets to determine to which output port of the router the data packet should be routed. In one embodiment, the systolic array pipeline includes a plurality of programmable functional units and register files arranged sequentially as stages, for processing packet contexts (which contain the packet's destination address) to perform operations, under programmatic control, to determine the destination port of the router for the packet. A single stage of the systolic array may contain a register file and one or more functional units such as adders, shifters, logical units, etc., for performing, in one example, very long instruction word (vliw) operations. The processor may also include a forwarding table memory, on-chip, for storing routing information, and a cross bar selectively connecting the stages of the systolic array with the forwarding table memory.

Abstract: A method for routing and switching data packets from one or more incoming links to one or more outgoing links of a router. The method comprises receiving a data packet from the incoming link, assigning at least one outgoing link to the data packet based on the destination address of the data packet, and after the assigning operation, storing the data packet in a switching memory based on the assigned outgoing link. The data packet extracted from the switching memory, and transmitted along the assigned outgoing link. The router may include a network processing unit having one or more systolic array pipelines for performing the assigning operation.
