提出了一种适用于数据通路结构的全局异步局部同步（GALS）技术。它基于本地同步块的请求驱动操作。请求线的不活动状态由一个特殊的超时电路检测。当超时发生时，本地同步块的时钟被移交给本地环形振荡器。在此基础上，提出了一种实用的异步包装器的硬件实现方案。仿真结果表明，所提出的GALS架构的潜力和性能。
A novel Globally Asynchronous Locally Synchronous (GALS) technique applicable to datapath architectures is presented. It is based on a request-driven operation of locally synchronous blocks. Inactivity of the request line is detected with a special time-out circuitry. When time-out occurs, clocking of the locally synchronous block is handed over to a local ring oscillator. Based on this concept, a practical hardware implementation of an asynchronous wrapper is proposed. The simulation results presented demonstrate the potential and performance of the proposed GALS architecture.
