Independent reset of arbiters and agents to allow for delayed agent reset

摘要

A system includes two or more agents and a distributed arbitration scheme for the bus to which the agents are connected. Thus, an arbiter corresponding to each agent is provided. The arbiters are reset using a first reset signal, while the agents are reset using a separate reset signal or signals. The arbiters are concurrently released from reset when the first reset signal is deasserted, and may have a consistent reset state to provide for synchronization of the arbiters. The agents may be independently released from reset by the separate reset signals. Accordingly, the arbiters may be synchronized and may remain synchronized even if the corresponding agents are released from reset at different times, or are temporarily held in reset for any reason. <IMAGE>
