Abstract
The proposed address generating circuit of an ATM (asynchronous transfer mode) switch can support a plurality of service classes by use of a single LSI under such a management that the cell buffers are divided for each service class. That is, an address generating circuit of shared buffer type ATM switch for an ATM switch system comprises a plurality of address generating units (5) each for storing a routing tag indicative of a cell output port, an address, and class data indicative of a service class of each of data cells stored in shared cell buffers. When data cells are inputted to and outputted from the shared cell buffers, the routing tags and the addresses of the address generating units (5) each having matching cell class data are selected and used.
