automatic degenerate code generating circuit

Abstract

An automatic degenerate code generating circuit includes an internal code holding section and an internal code generating section. The internal code holding section stores an internal code with a degenerate number of bits at the address corresponding to an input code including an identifier or identifiers in an ATM cell. The internal code generating section generates an internal code corresponding to a new input code every time the new input code is supplied, and stores the internal code into the internal code holding section. Problems are solved of a conventional automatic degenerate code generating circuit in that it must register the internal codes in advance, which is time consuming, and in addition it takes a long time to retrieve the internal code from the internal code holding section.
