System and method for reducing crosstalk in on-chip networks using a contraflow interconnect and offset repeaters

摘要

A data connector includes two different sets of wires that transport data between components of a computer system. A first set of wires transports data from a first component to a second component. A second set of wires transports data from the second component to the first component. The first set of wires is interlaced with the second set of wires so that each wire in the data connector transports data in the opposite direction of one or more neighboring wires.

1. A system for transmitting data between components within an integrated circuit (IC), comprising:
a first IC component coupled to a first set of data connections and configured to transmit a first data signal across the first set of data connections; a second IC component coupled to a second set of data connections and configured to transmit a second data signal across the second set of data connections; and an interconnect that includes the first and second sets of data connections and is configured to transport the first data signal to the second IC component across the first set of data connections and transport the second data signal to the first IC component across the second set of data connections, wherein the first set of data connections is interlaced with the second set of data connections such that each data connection in the first and second sets of data connections transmits data signals in a direction opposite of a direction one or more adjacent data connections transmit data signals, and wherein the first set of data connections includes a first set of repeaters spaced at substantially regular intervals along the first set of data connections and configured to repeat the first data signal, the second set of data connections includes a second set of repeaters spaced at substantially regular intervals along the second set of data connections and configured to repeat the second data signal, and the first set of repeaters are offset from the second set of repeaters such that each repeater in the first set of repeaters resides approximately halfway in between two repeaters in the second set of repeaters.
