Abstract: Based on the concept of synchronizer and AC'97 audio protocol, this paper emphasizes synchronizer optimization from a system design view and the correct circuit synthesis method, which forms a multi-clock domain design method for AC'97 audio controller. Result analysis shows that the synchronization failure probability is effectively decreased with a little increase in circuit area for synchronizers, and the performance of the AC'97 audio controller is enhanced.
