verilog 代码. 经验证成功,可以作为标准单元库,为FPGA设计者使用.-Verilog code. Certified success, as a standard cell library for the use of FPGA designers.

说明：  数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)

picoblaze实现串口通信...难道一定要20个字吗?-implement uart communication base on picoblaze

Fun little FPGA that plays a portion of Habanera

该项目用来测量频率。它有三个范围，其中包括 0.01 赫兹 ~ 1 Hz，1 ~ 100 Hz 和 100 ～ 10000 Hz。这样的结果将是最好的程序能自动调节到最佳的范围内。这个项目是在 Altera 软件 8.1 上进行验证。

说明：  基于CycloneV FPGA与电阻网络的数模转换器代码，能够实现键控更改频率，通过ROM IP核存储波形数据。(Digital to analog converter code based on cyclonev FPGA and resistance network can realize keying change frequency and store waveform data through ROM IP core.)

说明：  掌握SDRAM数据读写、刷新、初始化以及FPGA串口收发时序，熟练FIFO IP核的生成和调用。(Master SDRAM data read and write, refresh, initialization and the timing of sending and receiving of the serial port of the FPGA, skilled in the generation and invocation of the FIFO IP core.)
