ABSTRACT:
A multi-processor multi-node system having access to a low skew clock to synchronize processing events. This system uses a SCI network to distribute a low skew signal to synchronize the time of century clock counters on the different nodes. These counters are periodically synchronized with a signal from a selected master counter, so that all nodes will maintain approximately equal counter values. A single bit in a SCI header of send, echo, or idle packet is routed to all nodes via a SCI ring. Since the bit is inserted in existing packets, the creation of a special synchronizing packet is not required. Moreover, since the bit travels over existing lines, additional signal paths or extra wire are not needed.
