Apparatuses and methods for deterministic pattern matching

A system comprising:

• a first memory to store a first pattern table comprising information indicative of whether a byte of input data matches a first pattern;
• and
• whether to ignore other matches of the first pattern occur in remaining bytes of the input data;
• one-byte match logic coupled to the memory, to determine, based on the information of the first pattern table, a one-byte match event with respect to the input data;
• a control unit to filter the other matches of the first pattern based on the information of the first pattern table;
• a data cache coupled to the first memory;
• and
• a second memory to store a program that perform further pattern matching on results from the one-byte match logic.

A method comprising:

• determining, by one-byte match logic, a one-byte match event with respect to input data, wherein the determining is based on a first pattern table comprising information indicative of
• whether a byte in the input data matches a first pattern;
• and
• whether to ignore other matches of the first pattern occur in remaining bytes in the input data;
• and
• generating an address for accessing an item in a pattern database.
