Building an FoC Using Large, Buffered Crossbar Cores

The latest improvements in CMOS technologies have eliminated buffered crossbar memory requirements. Combined with a novel microarchitecture approach, these new technologies allow for implementation of a combined input-crosspoint queuing (CICQ), single-chip 32 times 32 switch as the core for a future fabric on a chip (FoC). This switch operates directly on variable-size packets, reducing overall data path complexity and increasing effective bandwidth.
