以下是一个简单的Verilog代码示例,将一个4位输入的二进制代码转换为one-hot编码: module bin2onehot( input [3:0] bin_in, output reg [7:0] onehot_out ); always @(*) begin case(bin_in) 4'b0000: onehot_out = 8'b0000_0001; 4'b0001: onehot_out = 8'b0000_0010; 4'b0010: one...
ASIC设计作业 ——Verilog HDL 设计产生One_Hot Code 姓名: 学号: 班级:一、名词解释——One-Hotcode 独热码,在英文文献中称做 one-hot code, 直观来说就是有多少个状态就有多少比特,而且只有一个比特为1,其他全为的一种码制。通常,在通信网络协议栈中,使用八位或者十六位状态的独热码,且...
verilog的一种编码方式。独热(one-hot)码 所谓的独热码是指对任意给定的状态,状态向量中只有1位为1,其余位都是为0。n状态的状态机需要n个触发器。这种状态机的速度与状态的数量无关,仅取决于到某特定状态的转移数量,速度很快。当状态机的状态增加时,如果使用二进制编码,那么状态机速度会明显下...
个人感觉没什么优点,具体参见文章:“多位格雷码计数器的VerilogHDL描述方法”。 8bit格雷码计数器的代码: 1module gray_counter(2rst_n,3clk,4bin_cnt,//输出二进制,可用于同步时钟域的计算、比较等5gray_cnt//输出格雷码,可用于异步传输6);78parameter CNT_SIZE =8;910input rst_n;11input clk;1213output ...
Derive state transition and output logic equations by inspection assuming a one-hot encoding. Implement only the state transition logic and output logic (the combinational logic portion) for this state machine. (The testbench will test with non-one hot inputs to make sure you're not trying to...
有限状态机编码对比 独热码(One-Hot Encoding) 很多独热码使用方法都是错的,没有起到简化译码的效果 独热码编码的最大优势在于状态比较时仅仅需要比较一个位 There are3 main pointsto making high speed state machines by one-hot encoding: Use 'parallel_case' and 'full_case' directives on a 'case ...
Characteristics of this approach are obtained by this approach can offer more enhanced reliability than Binary or One-Hot state encoding. Nowadays, Vending Machines are well known among Japan, Malaysia and Singapore. This is due to the modern lifestyles which require fast food processing...
