VHDL CODE FOR SQUARE WAVE GENERATOR

VERILOG语言速查手册,与VHDL齐名的另外一硬件描述语言(verilog language manuals, and the other enjoying VHDL hardware description language 1)

 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.)

该例程是PC机通过FX2-CY7C68013-A的USB2.0控制芯片与FPGA实现通信。其中的工程和代码包括PC机上的USB固件程序、驱动程序、上位机程序，FPGA上的VERILOG通信程序。(The routine is a PC, through the FX2-CY7C68013-A of the USB2.0 controller chip and the FPGA to achieve communication. One of the projects and code, including PC, the USB firmware, drivers, FPGA' s Communication Program)

半带滤波器verilog源代码，主要用于采样率变换系统中，采用乘法积累加器，很好的例子，供大家参考(Half band filter verilog code, mainly for the sampling rate conversion system, use the multiplication accumulation adder, a good example, for your reference)

matlab随即图设计程序，应该比较有用，希望能申请会员成功吧。。(matlab then drawing design program)
