IF YOU RELY ON CONVENTIONAL I/O structures based on buses, switches, or linear tunnels, efficiently performing data communications between data-processing blocks of large systems can be difficult. When many subsystems are simultaneously sending and receiving data, it can be difficult to ensure on-time data delivery for any transfer, given the inherent uncertainty of how the other transfers may affect it. By spreading out the data traffic over an entire area of the design, 2-D I/O f...
