1. A protocol analyzer that stores traces captured from high-speed communication interface having a transfer rate of at least 1 gigabit per second, the protocol analyzer comprising:

  • an interface port that provides a connection to the communication interface;

    a trace buffer memory;

    logic circuitry that controls selective write operations of traces from the interface port to the trace buffer memory; and

    a hardware search engine that searches the entire contents of the trace buffer memory for a specified data pattern in less than 10 seconds.
