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： The scheduling of multiple request to be processed by a number of deterministic finite automata-based graph thread engine (DTE) workstations is processed by a novel scheduler. The scheduler may select an entry from an instruction in a content search apparatus. Using attribute information from the selected entry, the scheduler may thereafter analyze a dynamic scheduling table to obtain placement information. The scheduler may determine an assignment of the entry, using the placement information, that may limit cache thrashing and head of line blocking occurrences. Each DTE workstation may including normalization capabilities. Additionally, the content searching apparatus may employ an address memory scheme that may prevent memory bottle neck issues.

摘要： An apparatus, and corresponding method, for generating a graph used in performing a search for a match of at least one expression in an input stream is presented. The graph includes a number of interconnected nodes connected solely by valid arcs. A valid arc of a current node represents a character match in an expression of a character associated with the current node. Arcs which are not valid may be pruned. Non-valid arcs may include arcs which point back to a designated node(s), or arcs that point to the same next node as the designated node(s) for the same character. Typically, the majority of arcs associated with a node are non-valid. Therefore, pruning the non-valid arcs may greatly reduce graph storage requirements.

摘要： A method and apparatus for processing security operations are described. In one embodiment, a processor includes a number of execution units to process a number of requests for security operations. The number of execution units are to output the results of the number of requests to a number of output data structures associated with the number of requests within a remote memory based on pointers stored in the number of requests. The number of execution units can output the results in an order that is different from the order of the requests in a request queue. The processor also includes a request unit coupled to the number of execution units. The request unit is to retrieve a portion of the number of requests from the request queue within the remote memory and associated input data structures for the portion of the number of requests from the remote memory. Additionally, the request unit is to distribute the retrieved requests to the number of execution units based on availability for processing by the number of execution units.
