Methods, systems and computer readable media for wide bus pattern matching

A system for wide bus pattern matching, the system comprising:

• a network equipment test device including at least one processor, the network equipment test device further including:
• a plurality of pattern blocks configured to compare each n-bit portion of data received from a data bus during a first clock cycle to a plurality of different n-bit pattern portions, n being an integer equal to a smallest boundary in which a pattern can start on the data bus;
• a plurality of diagonal detectors for detecting matching pattern portions across the pattern compare blocks that are arranged in a diagonal;
• and
• a packet boundary detector for detecting when the matching pattern portions arranged in a diagonal indicate a matching pattern that falls within a set of packet boundaries and indicating a positive match when the packet boundary detector indicates that the matching pattern falls within the set of packet boundaries.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

• receiving, in a first clock cycle, a bus width of data from a data bus;
• using pattern compare blocks to compare each n-bit portion of data on the bus to a plurality of different n-bit pattern portions, n being an integer equal to a smallest quantity of data in which a pattern can start on the data bus;
• detecting, using a plurality of diagonal detectors, matching patterns across the pattern compare blocks that are arranged in a diagonal;
• and
• detecting, using a packet boundary detector, when a plurality of matching patterns arranged in a diagonal falls within a set of packet boundaries.
