用verilog编写串并转换器的程序,要有详细注识释 reg[7:0]data;reg[2:0]cnt;always@(posedge clk or posedge rst)if(rst)/复位高有效reg;elsereg[7:0],din};din是输入串行数据,假设输入数据高位在前这是一个移位寄存器always@(posedge clk or posedge rst)if(rst)cnt;elseif(din_valid)/输入串行时能有效if(cnt=7)cnt;elsecnt;计数器,用来计算移位次数,移位8次在以后产生一个有效数据elsecnt;always@(posedge clk or posedge rst)if(rst)dout;dout_en;elseif(cnt=7)dout;如果计数器记到7,那么输出一个有效的8位数据dout_en;elsedout;dout_en;用Verilog HDL设计一个4位串_并转换器,需要程序和一定的注释 module s2p(clk,rst_n,sdi,pdo);input clk;clock signal for serial data inputinput rst_n;system reset signal,negative valueinput sdi;serial data input,posedge clock signal value,high significance bit input firstoutput[3:0]pdo;parallel data outputreg[3:0]pdo;always@4102(posedge clk)beginreset signal valueif(rst_n=1'b0)begin1653pdo;endreset signal is not value,module workelsebeginpdo[3:0][2:0],sdi};shift register valueendendverilog并串转换和串并转换问题 always@(posedge pclk,posedge reset)beginif(reset)beginp;endelse beginp;endendalways@(posedge sclk,posedge reset)beginif(reset)ser_d;elsebeginif(x。7)begin{p,ser_d},p};endelse ser_d[0];endend这里编译器没报错吗?p有两种驱动还有隔离不同时钟域最好要用fifo的,我就在你的基础上改了`timescale 1ns/1nsmodule p2s2p(reset,pclk,sclk,din,dout);input reset,pclk,sclk;input[7:0]din;output reg[7:0]dout;reg ser_d;reg[7:0]d,p,q;reg[2:0]x;reg s;always@(posedge sclk,posedge reset)beginif(reset)beginp;endelse if(x=1)beginp;endelse beginp,p[7:1]};endendalways@(posedge sclk,posedge reset)beginif(reset)ser_d;elsebeginser_d[0];endendalways@(posedge sclk,posedge reset)beginif(reset)x;else beginx;endendalways@(posedge sclk,posedge reset)beginif(reset)s;else beginif(x=2)s;else s;endendalways@(posedge sclk,posedge reset)beginif(reset)d;else begind,d[7:1]};endendalways@(posedge sclk,posedge reset)beginif(reset)q;else beginif(s)q;endendalways@(posedge pclk,。串并转换是要实现什么功能? 对。就是把串口一个一个输入的数据用并口在若干(通常为8)根线上同时输出,达到更高的速率重金求基于FPGA的8位串并转换vhdl语言的代码! library ieee;use ieee.std_logic_1164.all;use ieee.std_logic_arith.all;use ieee.std_logic_unsigned.all;entity sc is port(clk,rxd:in std_logic;。
