Abstract
In a system where multiple controllers share a link interface but are not all (1) compatible with the same configuration of the physical layer or (2) using the same clocking, a configuration arbitration subsystem intercepts, organizes, and re-clocks configuration-access requests from the various controller agents. Priorities are assigned according to stored policies. The configuration arbiter grants configuration access to the top-priority agent, synchronizing the agent's message with the arbiter's clock. Lower-priority agents' messages are stored in command queues until they ascend to top priority. Besides preventing timing conflicts and streamlining the coordination of clocks, the configuration arbiter may provide access to physical-layer registers beyond the controllers' built-in capabilities to further optimize configuration.
