An integrated circuit device can include a core section coupled to a plurality of signal paths having a predetermined physical order with respect to one another. A configuration circuit can selectively connect each signal path to a corresponding one of a plurality of physical connection points to the IC device according to one of at least two different physical orders in response to configuration information.

Integrated circuit with reconfigurable inputs/outputs

A method may include, in response to a single command and an N-bit segment value, generating a search key comprising M segments for at least one of a plurality of different databases, the N-bit segment value forming different ones of the M search key segments according to a database configuration of the at least one database.

Processor with compare operations based on any of multiple compare data segments

Present embodiments allow a search engine to quickly save and restore state information to and from an external state memory when switching between multiple data flows by transferring the state information between the search engine and the external state memory in a parallel manner. More specifically, for CAM-based search engines configured according to present embodiments, the CAM array includes state information gating circuits that selectively allow state information stored in the CAM array's match latches to be transposed onto the array's bit lines and then read from the array using the array's sense amplifiers.

Content addressable memory device capable of parallel state information transfers

Content addressable memory device having state information processing circuitry

A processor device integrated circuit can include a plurality of storage locations logically configurable into at least one database. Such a database can include a number of records, record having a selectable size of up to F multi-bit segments, where F is an integer greater than one. A search key application circuit can apply a search key value of up to F multi-bit segments to the at least one database in response to receiving one search key segment value. The one search key segment can be applied as any of the F multi-bit segments according to a segment selection value.

An integrated circuit device can include a plurality of configuration storage locations each comprising at least one encoding field. Each encoding field can selectively enable at least one received data value to be encoded into an encoded data value prior to being applied to a corresponding block of the integrated circuit device. Each block can comprise a plurality of content addressable memory (CAM) cells.
