    摘要: A computer-readable instruction is described for traversing deterministic finite automata (DFA) graphs to perform a pattern search in the in-coming packet data in real-time. The instruction includes one or more pre-defined fields. One of the fields includes a DFA graph identifier for identifying one of several previously-stored DFA graphs. Another one of the fields includes an input reference for identifying input data to be processed using the identified DFA graphs. Yet another one of the fields includes an output reference for storing results generated responsive to the processed input data. The instructions are forwarded to a DFA engine adapted to process the input data using the identified DFA graph and to provide results as instructed by the output reference.

    摘要: A RISC-type processor includes a main register file and a data cache. The data cache can be partitioned to include a local memory, the size of which can be dynamically changed on a cache block basis while the processor is executing instructions that use the main register file. The local memory can emulate as an additional register file to the processor and can reside at a virtual address. The local memory can be further partitioned for prefetching data from a non-cacheable address to be stored/loaded into the main register file.

    摘要: Methods, systems and articles of manufacture of processing a multi-state attribute field query. One embodiment provides a method of processing a multi-state attribute field query, comprising instantiating a plurality of live objects; performing, by each live object, an attribute operation, wherein at least one attribute operation is a comparison operation associated with attributes of the query. The plurality of live objects access a global status storage area only when an operand of the comparison operation is null or error. In any case, execution control is passed from each live object to an adjacent live object.

    摘要: A control lever assembly with handle lockout capability including a lever element selectively positionable in a locking position and lockable therein by movement of a handle thereof to a lock position. A first biasing member is disposed on the lever element in an operative position to exert a first biasing force against a detent element, and a second biasing member is disposed in opposition to the first biasing member and is operable to hold the detent element to allow free pivotal movement of the lever element relative to a base.
