A pattern of all 0's cannot appear when the taps use XOR gates. Since 0 XORed with 0 will always produce 0, the LFSR will stop running.注意初始化种子 A pattern of all 1's cannot appear when the taps use XNOR gates. Since 1 XNORed with 1 will always produce 1, the LFSR will sto...
这些挑战涵盖广泛的设计概念,包括组合与时序逻辑设计、具有不同需求的有限状态机、诸如排列、左移和循环移位等操作,以及多路复用器(MUX)、随机存取存储器(RAM)、线性反馈移位寄存器(LFSR)、加法器和计数器等基本组件。图5至图7分别展示了基础、中级和高级问题的示例。这些示例通过CodeGen-16B-FT生成,并经过编辑以确保...
but achieves very high speed with very simple logic, easily packing two bits into every CLB. Such Linear Feedback Shift-Register (LFSR) counters are also known as pseudo random sequence generators.
LFSR的初始值被称为伪随机序列的种子,其最后一个触发器的输出就是一个周期性重复的伪随机序列。 5.格雷码Gray Code 5.1 格雷码转二进制码 Gray code to binary code modulegray_to_binary#(parameterPTR=8)(gray_value,binary_value);//***input[PTR:0]gray_value;output[PTR:0]binary_value;//***wire[P...
