Abstract
A signal is transmitted from a sending chip to a first receiving chip in a communications ring via a first i/o set of the sending chip. A signal from the sending chip to a second receiving chip in the communications ring is transmitted via a second i/o set of the sending chip. The first i/o set corresponds to a first direction for the sending chip transmitting around the ring, and the second i/o set corresponds to a second direction for the sending chip transmitting around the ring. 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. The transmitting via the second i/o set is for a circumstance where the number is greater. For a chip interposed between the sending and receiving chips, the transmitting includes traversing from one of the first and second i/o sets of the at least one interposed chip, to the other one of the first and second i/o sets of the at least one interposed chip. The signal traversing the at least one interposed chip is regenerated by the interposed chip.
