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, ca- pable of handling 16 multiplexes carrying ATM cells at 622 Mb/s. It is a fully autonomous switch, i.e., the chip includes clock adap- tation, routing, and cell buffering as well as header translation and control capabilities. The switch is integrated into one single chip containing 6 000 000 transistors implemented in a 0.5- m CMOS process.
