Abstract
A method and apparatus for identifying framing bits embedded in an ATM frame significantly improves performance by logically comparing multiple bit slices in parallel to identify framing bits. Bits are received from a sequential input stream (64) to form an ordered collection of bits, included (66) in a frame bit history. The remainder of the bits separating framing bits are ignored (68). A second group of bits is received (70) to form another ordered collection of bits of the same size. This ordered collection of bits is included (74) in the frame bit history. Bits in the sequential input stream are again ignored (80). A third group of bits is received (82) to form another ordered collection of bits, and is included (88) in the frame bit history. The various ordered collections of bits saved in the frame bit history are logically compared (90) to determine (92) whether any of the corresponding bit slices could possibly constitute framing bits.
