Abstract
The architecture and operation of a self routing crossbar switch with multiple channels per input and output ports is described in this paper. The crossbar is the building block for an Asynchronous Transfer Mode switch fabric using delta networks with multiple links and shared output buffers. Each crossbar switch concurrently processes bitserial packets, using the packet headers for path setup and arbitration. The architecture consists of a pipeline of sorting and routing cells which permit high speed routing of the packets. A prototype 4×4 crossbar with 2 channels per port has been designed in 2μ double-metal single-poly CMOS and simulations indicate an operating speed of 50 Mhz. The design and implementation of the sorting and routing cells and the switch architecture that accommodates them is described in detail.
