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－从型结构的速度。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。 Linear feedback shift register (LFSR) is widely used in many areas such as spread spectrum communication, built-in self-test and digital encryption. In order to realize the physical realization of this type of circuit, a new type of structure for realizing high speed linear feedback shift register by using dynamic bilateral edge trigger is proposed. Get twice the speed of traditional master-slave architecture without increasing the cost of the circuit. On this basis, the proposed dual-phase parallel structure, from the theoretical analysis, can get the highest displacement speed.
