| 摘 要： | 提出了一种可重构线性反馈移位寄存器的设计。在设计中,针对Fibonacci和Galois两种类型的反馈结构分别采用了可重构的设计,并且支持混合反馈结构,线性反馈移位寄存器反馈抽头和插入点可选,长度可变并且可以通过链接支持超长线性反馈移位寄存器。在XC5VLX30器件上实现延时为4.808ns,LUT和触发器的个数为2279和1575。能够用于伪随机序列生成等应用。

| Abstract: | For Fibonacci and Galois feedback structures a design of reconfigurable linear feedback shift register is proposed, which supports the mixture of the two structures, with selectable insert point, feedback point and length of the register, and by link connection, also support the super-length linear feedback shift register. The delay of its implementation on XC5VLX30 is 4.808 ns, and the numbers of LUT and Flip-Flop in it are 2279 and 1575 respectively. It could be applied to the generation of psedo-random sequence and so on. |
