DDR3 SDRAM模块

用FPGA开发板的按键作为电子表的时间初值设置控制信号，数码管当前时间值输出。用按键选择分别输出：分、秒、1/10秒。(With FPGA development board button, as the time value of the electronic table, set the control signal, digital tube current time value output. Select output by buttons: minutes, seconds, and 1/10 seconds.)

Cores are generated from Confluence a modern logic design language. Confluence is a simple, yet highly expressive language that compiles into Verilog, VHDL, and C

用Verilog实现的交通信号灯控制，主干道和支路通行的时间不相等(Using Verilog implementation of traffic signal control, the trunk road and the slip is not the same passage of time)

使用vhdl语言设计一位全加器，在仪器上下载并实现LED灯的闪亮(A full adder design)

GPIO LED 测试工具源代码，可以用来检测开发的主板GPIO LED设备是否工作正常(GPIO LED test tool source code, can be used to detect the development of motherboard GPIO LED device is working properly)

The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data. The 720-channel source driver has true 6-bit resolution, which (The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data.

 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.)
