High speed programmable ATM-HUB for HIPPI/STM-4 data network

A programmable ATM-HUB is developed to realize high speed ATM communication by utilizing the full bandwidth of 155/622 Mbps on an STM-1/STM-4 transport system. High performance workstations can connect to this system via 800 Mbps HIPPI and 155/622 Mbps optical lines. The ATM-HUB's main circuits consist only of FPGAs and memory. The ATM-HUB's wired logic is programmable, making it possible to implement various kinds of higher level transport protocols on the reconfigured wired logic. All functional designs for the ATM-HUB can be performed by the purely text based hardware description language and high level logic synthesis CAD.
