This paper briefly describes the problematic metastability in the asynchronous designs and presents a regular solution——synchronizer.

本文主要就异步设计中涉及到的亚稳态问题,作简要介绍,并提出常用的解决办法——即同步器的使用。

Two methods of polarization now: spin exchange and metastability exchange are reviewed.

介绍了目前极化惰性气体常用的两种方法——自旋交换光抽运和亚稳态能级交换。
