标准的异步串口通讯设计程序――基于VHDL编程

说明：  这是32位移位寄存器，是用verilog编写的，能够实现从1到31位的左或右的移位(This is a 32-bit shift register, is prepared verilog, can be realized from the 1-31 shift left or right)

串联型有源电力滤波器的 PSCAD仿真，能检测到谐波电压，本仿真的优势是能针对电压跌落或者升高进行自动补偿。(PSCAD simulation of Series type APF (Active Power Filter),this project can dectect the drop of voltage and compensates auomaticly.)

HDB3码在matlab中的仿真，包括原始码、AMI码及HDB码的相关仿真图形(HDB simulink in matlab)

 交通灯控制器控制红（r）、绿（g）、黄（y）三种不同颜色的交通灯，这三种不同颜色灯的亮、灭分别由三个定时器（timer1、timer2、timer3）控制；  当某个定时器工作时，它所控制的交通灯亮，直到设定的定时时间到（该定时器状态由’0’变’1’），交通灯跳转到另一种状态；  clk是脉冲控制端（图中未标出）；reset是异步复位端，复位状态为红色交通灯亮；  输出端r、g、y分别表示三种颜色交通灯的亮、灭状态。 ( traffic light controller control red (R), green (g), yellow (y) three different colors of traffic lights, three different colors of bright lights, off by three timer (Timer1, Timer2, Timer3 ) control  When a timer work, it controls the traffic lights, until the set timing (the timer status ' 0 ' for ' 1' ), traffic lights Jump to another state  clk is the pulse control terminal (not shown) reset is asynchronous reset terminal, the reset state for the red traffic lights  output terminal r, g, y represent the three colors of traffic lights bright, the off state.)
