Adaptive synchronization

Delay variations are typically accounted for by increasing cycle time margins. Adaptive synchronization eliminates this on inter-modular interfaces in very large, high performance chips. The chip is divided into multiple smaller synchronous modules. Multi-synchronous hierarchical clocking provides t...

Zusammenfassung:Delay variations are typically accounted for by increasing cycle time margins. Adaptive synchronization eliminates this on inter-modular interfaces in very large, high performance chips. The chip is divided into multiple smaller synchronous modules. Multi-synchronous hierarchical clocking provides the same frequency to all modules, but does not maintain any particular phase. Adaptive synchronizers adapt to the time-varying inter-modular clock and data phases, and out-perform conventional synchronizers.
