The architecture of a 32-channel, 200 MHz Batcher-Banyan fabric chip for broadband ATM packet switching is described, as well as the design methods required to develop a 380 K-transistor CMOS device that operates at these speeds under worst-case conditions. This device routes packets from 32 sources to any 32 destinations, is completely reconfigured each packet period, maintains priorities, supports contention resolution, and is a building block for larger switches.>
