High radix self-arbitrating switch fabric with multiple arbitration schemes and quality of service
A scalable architecture to design high radix switch fabric is presented. It uses circuit techniques to re-use existing input and output data buses and switching logic for fabric configuration and supporting multiple arbitration policies. In addition, it integrates a 4-level message-based priority arbitration for quality of service. Fine grain clock gating, tiled fabric topology and self-regenerating bit-line repeaters enable scaling the router to 8k wires. A 64×64(128b data) switch fabric fabricated in 45nm SOI CMOS spans 4.06mm2 and achieves a throughput of 4.5Tb/s at 3.4Tb/s/W
