摘要:
In a bus system including a bus, a plurality of nodes including a primary node, and a bus access coordinator, bus utilization efficiency is improved by operating the coordinator at the same clock frequency as the primary node. The primary node is the node in the bus system which accesses the bus most frequently. By running the coordinator synchronous with the primary node, the need for synchronization events between the two components is eliminated. Since the primary node accesses the bus most frequently, eliminating synchronization events with the primary node eliminates most of the synchronization events in the bus system. Thus, synchronization events are minimized which, in turn, improves bus utilization efficiency.
