Abstract:
A method of communicating among chips coupled in a communication ring on a multi-chip module, comprising the steps of:transmitting a signal from a sending one of the chips to a first receiving one of the chips in the communications ring via a first i/o set of the sending chip; and transmitting a signal from the sending chip to a second receiving one of the chips in the communications ring via a second i/o set of the sending chip, wherein the first i/o set corresponds to a first direction for the sending chip around the ring and the second i/o set corresponds to a second direction for the sending chip around the ring, and the transmitting via the first i/o set is for a circumstance where a number of chips interposed in the ring between the sending and receiving chips in the first direction is not greater than the number of chips interposed in the second direction, and the transmitting via the second i/o set is for a circumstance where a number of chips interposed in the ring between the sending and receiving chips in the first direction is greater than a number of interposed chips in the second direction.
