    Abstract: Approaches for a packet format for error reporting in a content addressable memory (CAM) device are disclosed. The CAM device may comprise a CAM array that includes a plurality of rows, each row including a plurality of CAM cells coupled to a match line, and an error notification circuit capable of forming a packet that indicates whether the CAM device is experiencing an error condition. If an error condition was experienced by the CAM device, the response packet may also indicate the type(s) of error that was encountered. Advantageously, information about any error condition experienced by the CAM device may be quickly ascertained by a host device in which the CAM device is incorporated.

    Abstract: A receiver circuit for coupling to a serial link is disclosed. The receiver circuit comprises a data buffer and serial interface circuitry. The serial interface circuitry receives serialized packet words and processes the serial words for input to the data buffer. The serial interface circuitry includes word detection logic to detect predefined control words and discard logic to selectively inhibit forwarding of one or more of the predefined control words to the data buffer.

    Abstract: A method is disclosed for handling packet data. The method includes assembling request packets for transmission along a plurality of serial lanes. For each lane, at least a portion of the request packets are framed into a request link frame having a plurality of words. The request link frame is defined by a preset word length. Request training words are inserted into the request link frame at intervals corresponding to the preset word length. Response packets are queued, where the response packets include response training words having an associated latency based on the programmed interval of the request training words.

    Abstract: An integrated circuit is disclosed. The integrated circuit includes a receive port interface to receive request data at a first data rate from a first host and a transmit port interface. The transmit port interface to transmit response data words across plural serial lanes to a second host at a second data rate. The second data rate is less than a predefined line rate of symbol transfers across the plural serial lanes. The transmit port interface includes shaping logic to transmit a data word stream at the second data rate and selectively insert idle words into the data word stream such that the data words and the idle words are together transferred at the predefined line rate.

    Abstract: A content search system including a CAM device having a plurality of CAM blocks and a governor logic receives a search request and compares the number of CAM blocks required to perform the requested search to a limit number, the limit number being the maximum number of CAM blocks permitted to be used in a requested search operation. If the number of CAM blocks required to perform the requested search exceeds the maximum number of CAM blocks permitted to be used in a requested search operation, then the search operation is rejected. The governing operation can be performed on each requested search, thus limiting power dissipation. The relationship between a maximum number of CAM blocks and power dissipation can be characterized, and a corresponding block limit value can be stored into a memory accessible by governor logic.
