Abstract: A scalable low-latency switch extends the functionality of a multiple level minimum logic interconnect structure for usage in computers of all types, networks and communication systems. The multiple level minimum logic interconnect structure employs a data flow technique based on timing and positioning of messages moving through the structure. The scalable low-latency switch is distributed throughout multiple nodes in the structure so that a supervisory controller providing a global control function and complex logic structures are avoided while the interconnect structure operates as a “deflection” or “hot potato” system in which processing and storage overhead at each node is reduced. The interconnect structure using the scalable low-latency switch employs a method of achieving wormhole routing through an integrated circuit chip by a novel procedure for inserting messages into the chip.
