| 摘 要： | 文章基于传统的部分译码桶式移位器,对其关键路径进行了改进,根据移位的特点,引进了一种逆序变换方法以达到数据路径与控制路径的平衡,并据此提出了一种折叠式的电路结构以减少连线延迟和面积,改进后BS的关键路径由一级三输入与非门和一级缓冲器组成,实现高速桶式移位器设计。用SMIC0.13!m/1.2V工艺仿真结果显示新结构的桶式移位器的关键路径延迟为0.5ns,比传统结构延迟时间缩短了38%。

| Abstract: | Compared with the traditional barrel shifter, this paper focuses on how to reduce the critical path length so that the high-speed of BS can be reached. Through introducing a converse transform circuit, the data path between input data signal and control signal has been balanced. In order to reduce the length of wiring, the Fold Structure is used in the shift array circuit design. |
