| 摘 要： | 线性反馈移位寄存器（ＬＦＳＲ）被广泛用于扩频通信，内建自测试和数字加密等许多领域。文中针对这一类电路的物理实现，提出了利用动态双边沿触发器实现高速线性反馈移位寄存器的一种新型结构。在不增加电路代价的前提下，获得了两倍于传统主－从铁速度，在此基础上，提出双相并行结构，从理论上分析，可得到最高的移位速度。

| Abstract: | A high-speed linear feedback shift register (LFSR) has been implemented in a novel architecture, which,using a double-edge triggering dynamic flip-flops, can achieve a double performance with no extra hardware cost, when compared with conventional master-slave flip-flops. A two-phase parallel architecture is also proposed, which can achieve the possible maximum speed. |
