Abstract
The invention is a state machine for the detection of a pre-specified pattern of m bits in a stream of bits where the stream of bits is examined in steps, each successive step consisting of the examination of the next successive set of n bits in the stream of bits. The state machine is mechanized by a look-up table. The current set of n bits is combined with a state number representing the current state of the machine to obtain an address for entry into the look-up table. The state number stored in the table at that address is the new state number representing the new state of the machine after the examination of the current set of n bits in the stream. The new state number is then combined with the next successive set of n bits to obtain the next new state number from the table. Thus each new state number becomes the current state number for combination with the next set of n bits to form the address for entry into the table. The process is continued until the state number indicates that the pre-specified pattern of m bits has been detected in the stream of bits.
