    摘要： Disclosed herein is a method and system for accelerating the generation of pattern indexes. In exemplary embodiments, regular expression pattern matching can be performed at high speeds on data to determine whether a pattern is present in the data. Pattern indexes can then be built based on the results of such regular expression pattern matching. Reconfigurable logic such a field programmable gate arrays (FPGAs) can be used to hardware accelerate these operations.

    摘要： A high speed technique for options pricing in the financial industry is disclosed that can provide both high throughput and low latency. Parallel/pipelined architectures are disclosed for computing an option's theoretical fair price. Preferably these parallel/pipelined architectures are deployed in hardware, and more preferably reconfigurable logic such as Field Programmable Gate Arrays (FPGAs) to accelerate the options pricing operations relative to conventional software-based options pricing operations.

    摘要： Disclosed herein is an improved architecture for regular expression pattern matching. Improvements to pattern matching deterministic finite automatons (DFAs) that are described by the inventors include a pipelining strategy that pushes state-dependent feedback to a final pipeline stage to thereby enhance parallelism and throughput, augmented state transitions that track whether a transition is indicative of a pattern match occurring thereby reducing the number of necessary states for the DFA, augmented state transition that track whether a transition is indicative of a restart to the matching process, compression of the DFA's transition table, alphabet encoding for input symbols to equivalence class identifiers, the use of an indirection table to allow for optimized transition table memory, and enhanced scalability to facilitate the ability of the improved DFA to process multiple input symbols per cycle.

    摘要： Disclosed herein is a method and system for integrating an enterprise's structured and unstructured data to provide users and enterprise applications with efficient and intelligent access to that data. Queries can be directed toward both an enterprise's structured and unstructured data using standardized database query formats such as SQL commands. A coprocessor can be used to hardware-accelerate data processing tasks (such as full-text searching) on unstructured data as necessary to handle a query. Furthermore, traditional relational database techniques can be used to access structured data stored by a relational database to determine which portions of the enterprise's unstructured data should be delivered to the coprocessor for hardware-accelerated data processing.
