Abstract:
A switching system for switching a fixed-length cell composed of a header section and an information section between a plurality of incoming highways and a plurality of outgoing highways based on information included in the header section of said cell, comprising:a first storage for storing cells received from said plurality of incoming highways and switching said cells to a destination outgoing highway of said plurality of outgoing highways;a second storage which stores information corresponding to an idle address of said first storage;a third storage which stores information from said second storage as a next address for writing a next cell in said first storage; anda control circuit which controls write and read operations of said first storage corresponding to information stored in said second storage,wherein said control circuit, installed in common to said first storage and said second storage, is connected so that information corresponding to an idle address of said first storage is stored in said second storage based on a read address of said first storage from said control circuit and information from said second storage is output as a write address of said first storage, andwherein said control circuit inputs said next address as an address corresponding to a write address of said third storage at a time of writing a cell into said first storage and outputs a read address of said first storage based on said next address output from said third storage at a time of reading a cell from said first storage.
