4 位纹波计数器

这主要是学习vhdl和fpga设计的一些资料(study for vhdl and fpga)

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.)

xilinx FPGA 与高速ADC LVDS接口的范例程序(xilinx FPGA ADC LVDS interface)

design and implementation of a format conversion system on the Altera NIOS board(QUARTUS) which reads an analogue input, converts it into digital data, and then does the reverse conversion back into analogue format. This will be done by taking an analogue an analogue input using SPI MCP3202 12-Bit A/D converter to generate the digital data stream and then the digital data will be used to generate an analogue output using Analog Devices 8-bit SPI AD7303 D/A converter.
