本文提出了一种新的设计大型低功耗异步系统的方法和算法。该系统是由一个商业工具合成的同步电路，并随后转换成一个异步。转换算法包括提取输入输出集、替换存储元素、识别分叉集和连接集、构造请求网络和应答网络。采用了双锁存异步流水线（Double-Latched Asynchronous Pipeline）结构。由此产生的异步电路可以使其有效工作频率适应电源电压，从而实现灵活高效的电源管理。该算法已在多个电路上得到验证。
A novel methodology and algorithm for the design of large low-power asynchronous systems are described. The system is synthesized by a commercial tool as a synchronous circuit, and subsequently converted into an asynchronous one. The conversion algorithm consists of extracting input and output sets, replacing the storage elements, identifying fork and join sets, and constructing request and acknowledge networks. A DLAP (doubly latched asynchronous pipeline) architecture is employed. The resulting asynchronous circuit can adapt its effective operating frequency to the supply voltage, facilitating flexible and efficient power management. The algorithm has been validated on several circuits.
