A 16/spl times/622 Mb/s ATM switch: PRELUDE switch architecture integrated into a 6-million transistor monochip

This paper presents the integration of the Prelude switch architecture into a monochip ATM switch, COM16M, capable of handling 16 multiplexes carrying ATM cells at 622 Mb/s. It is a fully autonomous switch, i.e., the chip includes clock adaptation, routing, and cell buffering as well as header translation and control capabilities. The switch is integrated into one single chip containing 6000000 transistors implemented in a 0.5-/spl mu/m CMOS process.
